Is there an agreement or something in the handbook that describes themes for series? At least, I don't understand why they are removed quite often. Here: #11252729 but not here #11551531 . Here the most: #11542629 , #11542593 , #11542573 and here again not #11542019 . So the image varies quite a bit across the Beleef de natuur series.

That is why I do not collect machines, nor do I sell them, but give them away to enthusiasts; I still have hundreds. On the general site, such as LD, I probably misidentified this stamp, so I will remove it from my shop and put it through the paper shredder.

vertigo I completely agree. That is also why I am cautious about the idea. You don't want a single party offering at 'dump prices' to immediately drive down the catalog value. That is why the principle only works with sufficiently large sales volumes, so that a true 'market average' is established.

Charles1971 Well, I’m quite willing to put that on the list of discussion points. The fact is that the situation regarding stamps isn't really about the 'condition' of the stamp. You can have a used stamp in perfect condition, without damage and with a clearly legible cancellation mark, but also a mint stamp where three perforations have broken off. To really say something about the condition, you would actually need to add a second axis. But if you introduce 5 gradations into that, you’re already at 15 values.

I think the current assumption is that the catalogue values apply to stamps in perfect condition (mint, unused, or cancelled) and that you take a percentage of that based on the actual condition. What those percentages are and how they vary between stamps is undoubtedly also a source of discussion. Personally, I doubt whether it would help to record all those values separately in the catalogue, but I will throw it out to the group. I wanted to leave it at that for now, as this topic was not specifically about postage stamps.

If you give people this advice

If you lack knowledge of this rather complex subject matter, I would advise machine suppliers to take another good look at what is on offer and/or purchase a special catalog of Machins for 60 English pounds, or remove them from your shop to avoid problems later on.

It might be a good idea to ask yourself whether a similar remark does not apply to your own offer.

After all, specialists distinguish two variants of the £10 stamp at a fairly elementary level. Connoisseur even knew of three catalogue numbers for it. You can hardly blame people who are not interested in variants for not having a special catalogue. The consequence, however, is that you get the mess described here for the Machins. But that mess occurs for many more series (Wildings, MacKennals) and even countries.

SG Concise is still a relatively basic level. Most people who collect British stamps have Michel or Yvert and have no idea of most variants, or of SG Concise, which is also very limited in its variants. And even if someone has SG Concise, they still need to understand the differences that are actually included.

If you want to buy specialized stamps, you must go to a specialized site or inquire with the provider. On general sites, you can bet your life that many stamps are misidentified. The fact that someone enters an MPIL/M18L stamp does not mean that others realize it is a variant. The first one someone finds resembles their stamp might well end up in their collection or shop.

Thank you for your response. I will perform the assessment as carefully as possible.

Catalog values will likely always remain a point of discussion, but with the history of sales prices, LD at least forms a unique point of reference.

I would like to make a small caveat here. In my opinion, you cannot simply copy the selling prices on LD. There are also private sellers among them who set the prices of their items lower than is reasonable because they want to get rid of their items very quickly (the race to the bottom). For that reason, where possible, I compare the prices with the asking prices of business parties.

What bothers me about the catalog values for stamps is tomdejong, there are too few of them.

In most categories, I already see 5 catalog values. For stamps, it is a meager 3.

In my view, you cannot summarize the different conditions of stamps in 3 catalog values.

At the same time, I predict that a great deal of discussion will arise if the catalogue value of many stamps were to drop to a few cents, because most sales are at that price level.

Collectors regularly wonder via the forum what value they should assign to their collection – you have now provided the answer yourself.

Harry56 Thanks for your nice comment! You describe exactly why I got so excited about LastDodo back then (when it was still Catawiki). Working together on the most complete catalog possible and being able to keep track of your collection and wish list very concretely based on that. Buying and selling indeed becomes much more targeted this way than when you have to endlessly search through textual descriptions of ads or auctions online. Apart from my current role, I am still happy when I can add something that wasn't in the catalog yet or cross an item off my wish list. Good to hear that you experience it that way too. Catalog values will probably always remain a point of discussion, but with the history of selling prices, LD at least forms a unique point of reference.

Oh yes, LD is certainly already using AI. In writing source code for functional adjustments, in tightening security against the endless stream of bots besieging the site, and even in creating overviews from the catalog. The development team behind LD continuously monitors new developments.

tomdejong Rene and everyone. For me, even though I have stopped actively selling, LD remains a unique collector's site. Whether you view it as buying or selling, or as the primary goal of documenting a collection in whatever way, makes no difference. I still occasionally buy something via LD or Catawiki myself, because otherwise a hobby stagnates, which is not an option for me either. Buying or selling via LD, with all its wonderful possibilities through a system connected to a catalog with images, is simply more fun than "auctions." And I can now imagine that keeping so many entered items up to date is impossible. Catalog value is just one part of the system. Thanks again for the feedback. By the way, I am curious whether LD is already using AI, because apparently everyone has to start believing in that. That aside.

Maybe I don't fully understand, or don't understand at all, what I am supposed to respond to now.
The stamp satisfies all the characteristics as described in the concise catalogue under no. SG 1658.
I cannot find a 2nd or 3rd printing of this stamp in the concise; if you could please provide the SG number.

I didn't expect my prediction to come true so quickly :-) I get your point Esquerdo.
The idea has been noted as a suggestion for discussion, but it is clear that it is not a panacea either.

When it comes to stamps, the vast majority sold on all kinds of websites is junk. Stamp prices always remain an issue. The advantage of a catalog value is that you have a starting point for a stamp in very good condition. Depending on the stamp being offered, you deduct a bit from that.

The average realized price is therefore by no means a good indication of the value of a stamp with a fresh appearance and a light, legible cancellation that does not cover the image. The quality of the sold stamps is unknown.

nlae The idea occurred to me while I was thinking about Harry56's suggestion. With sufficiently large volumes, it could indeed be a serious option (I will add it to the list as a development idea anyway). At the same time, I predict that a great deal of discussion will arise if the catalog value of many stamps were to drop to a few cents, because most sales are at that price level.

You might consider automatically deriving the catalog values from that sales history, but that runs into the problem that there are often no or very few sales of an item, whereas derivation would only work with large numbers.

Now you are only talking about books – For the stamp section, this could well be the solution – At the moment, that is a complete mess – 70% of the value based on the Michel and 30% entered based on sentimental value.

vertigo I didn't respond to your comment last week because I wasn't quite sure what to make of it. You are free to make your own judgment when reviewing. The premise is that you, as an administrator, have the expertise to evaluate suggestions. I can imagine that you base this on the standard of fixed ratios. René's and my position was simply that deviations from that are possible. These will need to be justified by the user making the suggestion, and then it is up to you to assess their value. It is all human work and therefore subjective, but it at least provides an indication to collectors (and the opportunity to make suggestions for updates).

Harry56 Your opinion is of great importance (just like that of all users), so apologies for missing your suggestion among all the messages last week. Rene has already responded, and I can only agree with that. You yourself already mention that historical sales values are perhaps the best indicator of the true market value. You might consider automatically deriving the catalog values from that sales history, but that runs into the problem that there are often no or very few sales of an item, whereas derivation would only work with large volumes. Undoubtedly, there are many incorrect or outdated values, but there is therefore always room to update them.

Top left: #7806599 . Other than that, no idea.

Top right: pickaxe and shoe indicate a mountaineer's or hiker's pin from Austria or Switzerland. A souvenir pin that was worn on a small hat. There are countless variations like this.


The bottom left comes from the former Czechoslovakia,
35 let = 35 years
SSŽ = Stavby silnic a železnic, a large former construction company from Prague (primarily roads and railways).
I cannot find a founding date, so no year of issue either.

Bottom right: Austin #585131

You may enter the two missing ones into the catalog.

There is a lot to say about many series. Unfortunately, that is difficult to reconcile with the definitions used here. That, and the fading of these kinds of threads, do not encourage the opening of such educational threads.

If you would like to know more about the basics of the Machines, the accompanying video might be of interest. It is a bit of a feature film, though.

And for those who consider this good advice:

If you lack knowledge of this rather complex subject matter, I would advise machine suppliers to take another good look at what is on offer and/or purchase a special catalog of Machins for 60 English pounds, or remove them from your shop to avoid problems later on.

You might want to consider whether this could also apply if you are offering a British £10 stamp.

35 years ago something in the Eastern Bloc (but not written in Russian). Thanks for thinking along.

Harry56 For me, it is mainly about comic albums that many collectors are still looking for, and which are not offered by any or only 1 or 2 sellers. So for me, it is usually a matter of adjusting the price to the supply/demand for a slightly higher price. Consequently, these are usually the hard-to-find albums. Also, check the LD retail price yourself to see what value they were offered for in the past.
