Another good vintage find from my LCS

This is another vintage round I picked up the other day. I love these rounds - but get frustrated with my inability to find information about who minted it. I know International Silver Trade Units were popular at the time in the late 70's and early 80's but I hope someone knows more about it.

I like the reverse design a lot, it clean looks great. I have seen a few of these sold on Ebay for a premium, but there are so few of them, I can't tell if it was a fluke or it actually represents the market price.

Thats about all I got today. Just a another solid add to the stack that some day I may sell for a profit to stack more weight. Either, silver is cheap in my mind and I can always use a few more ounces!!

Stack on!! _Senstless
