An unknown number of years ago, someone gave me a stack of 75 glassine envelopes containing some 222 foreign stamps, which I do not collect. So for decades now, they have remained stashed away in their envelopes virtually untouched. My problem is how to identify them, and determine if they are worth the effort to try to sell.
There are notations on the glassines that are both for, I think, categorizing purposes, as well as identification. I have scanned several of the glassines with the stamps in them and the markings on the envelopes for your consideration.
Are those
Scott numbers for the countries stamped on these glassines?
What period of history do they come from? (I'm guessing 1950's and/or 1960's.)
Is there a way I can verify the identification and current price of 222 stamps from 12 different countries without spending a fortune?...Online sources possibly?... The prices listed on the envelopes are from God knows when. With the current prices, is it even worth the effort?
Here are the countries and the number of stamps each:
Chile- 34
Cuba- 14
Brazil- 11
Dominican Republic- 32
Honduras- 10
Ecuador- 3
Mexico- 2
Costa Rica- 3
Bolivia- 31
Columbia- 39
Nicaragua- 20
Argentina- 23





Can anyone identify this one?
Thanks for any help!
