I'm no where near an expert but my guess is that the seem to be all shoot the word is on the tip of my tounge anyways it means that they are very common stamps and alot were distributed but lets let one of the knowledgeable guys give there opinion is that word definitives?

These are mostly pretty common stamps; I don't think any are very valuable, except maybe the Greece stamp (I'll have to look that one up). Also, some of them are damaged (particularly the India and U.S. stamps), so that would take away from their value.

Besides the Greece stamp, you might want to check the early Australian George V stamps (watermarks+plates). These are mostly very cheap stuff, but there are exceptions... As for Belgium, the 1911 "fight tuberculosis" stamps are slightly better ones (even hinged).

The Greek stamp looks like a Scott #64, though it could also be a #90a. Either way, its used value is around $1.

Value is not always measured in dollars. If it has sentimental value no amount of money matters!
