Hi all, I'm new here. I didn't even realize what the Gengshen monkey stamp was until yesterday. Glad I found the forum!
I actually just came across one of these by luck while out treasure hunting at auctions. I bought a stamp collection at an estate auction (and watched the wife flip a bit when she found out how much I paid!). In fact, it was even better. All I was buying it for was the domestic US stamps, and folded up in the binder were 4 old chinese presentation stamp sets. This and many other rare and high value sets (Opera singers, the horses, scientists) were in the sets, and a lot of Mao, Stalin, Marx, Lenin and other communist propaganda.
Wife insisted I at least make our money back before I get to move any of the stamps into my collection, so they are up onto "her"
ebay account. :)
Thankfully the collection is pretty extensive, so it will keep me busy for quite some time - cutting into my treasure hunting (and spending) as the wife views it.
This collection has a lot of foreign stamps which I really am not into, so if you have a wish list - let me know. The domestic collection goes all the way back to Scott #11, and the foreign ones appear to go way back as well.
You will see more of me soon.
Cheers!
