Need Stamp Number Estimation By Weight

Some dealers sell stamps by weight.
Can you estimate, from your experience, how much 1000 stamps weigh, on and off paper? Grams will be better.
Thanks
Rob

1000 stamps (mixed commentative/definitive, off paper) = 96 grams

Are you sure? In ebay, a dealer offers 90 grams and estimates it as 2000 stamps. If you're right, that's a very big lie.

Unless he's offering mainly definitive, which doesn't show in his scans.

I sell my extra WW off-paper stamps to 2 people at 1000 stamps = 96 grams (they take everything that I accumulate each year).
I've counted them a few times in the past and am probably underestimating the count a bit (I am not a dealer and am more interested in passing along material). These tend to be heavy on commentatives; probably 70% commentative and 30% definitives. A mix that has has more definitives would give you a higher count. For example, I just weighed 1000 US Washington/Franklins stamps and it came out to 55 grams. (But that makes sense, a definitive is about 50% the size of a commentative.)

Since you are so doubting, you could assemble a very small group of off-paper definitives yourself, weigh them and scale up. You are given an answer to a question you asked and choose not to believe, once again.

The seller says 1800-2200 stamps off-paper, not 2000 guaranteed. Would you give the seller a negative if the count was 1797 excluding added extras? Perhaps it would be for the best for you to stay off ebay?

The seller notes that he/she is always getting new material, so it may be inferred that the image given is just a sample view.



There are almost nothing but definitives in the one image shown. It is almost all bundleware so there will be basically quite common stamps included, with duplication. The other scans show details of the main scan. Again, it might not be a current view of what's being sold.

It definitely depends whether you're dealing with small definitives, a healthy WW mix, or mixes with a lot of "big Stamp countries" (ie 1950+ Russia/Mongolia/Hungary/etc). As an example, there is approx 35 Canadian Admiral stamps per gram (at least what my scale reads anyway) so that equates to only around 30-35g per 1000. Start adding 1950+ CDN stamps and you can at least double that into the 70-100g per thousand. I would agree with Don on a rough avg of around 90-100g per thousand but that's assuming it is a very wide variety of everything.

There is also oodles of other factors such as scale calibration, do they first minus the object they place the stamps on when that's on the scale, are they all hinged on the back, maybe bits of paper still stuck, Etc etc. The odd one may affect the number by next to nothing but if an entire batch has a commonality, it will change the numbers.

At the end of the day, if you want to really know, maybe just buy a single lot and see what you think. If it isn't to your satisfaction, seek a different seller. That said, as was pointed out above, each lot May be very different given that it is based on what material the seller acquired.

hy-brazil, chill.
I wasn't doubting Don's answer, I was surprised by the big difference: The dealer offered twice the amount that Don knew to be true.
When Don measured only definitive (Washington/Franklins stamps, no doubt small definitive) it came out to 110 grams for 2000 stamps, not 90 grams.
Finally, I looked at that dealer's feedback, and read "Although advertised as 2000 plus WW Stamps, this was about 1500 common...". So it seems that the dealer wasn't too "kosher".
As to whether or not I should buy at ebay - I didn't ask for any opinion on that.

I guess a person could also be like a dodgy pot dealer; easily increase the weight by a few grams with a mist bottle of water...

stamps101 - I understand that it's only an estimation, and that's what I asked for.
As you can see, that dealer took some liberties, offering 2000 stamps but sending only 1500. On the other hand, selling stamps by weight should be, for me at least, a warning sign.

If some of the stamps are CTO, the dealer may consider them used, yet the gum on the back weighs a good portion of the stamps' total weight. 1/3 CTO (with gum on the reverse) can pump the weight up significantly. If you are seeing 2000 stamps at 90 grams, then gum is probably not a big problem. Many collectors would say that gum should not be a problem at all on a pile of used stamps.

also, some stamps are printed on thicker paper than other stamps, it's an impossible question to answer.

i would imagine there's a lot of faulty stamps, questionable quality and very doubtful there's any good stamps.

i usually sell my faulty/less attractive stamps in cigar boxes on auction with the label, all qualities exist.
