Picked this up at the coin show too. The dealer left it in the flip it was in when he purchased it. The previous owner had documented the day he purchased it. And the dealer he bought it from also dated when he marked it for sale. So $11.50 in 1965. Although the other writing is confusing. "Both Crises"? "Rabbit and Hanging Cloths"? Who knows.
It was in a case that was all silver rounds. So when I saw a price of $11.50 I assumed that it was a round too. But it looked too much like an actual Trade dollar. So I asked. Glad I did. Of course the other price on there was the real one. But the dealer came down quite a bit from that.
I forgot my loop so at the show I thought maybe BU. But when I got home I thought more of a high AU. What do you guys think?
