Aloha, just saw where a 1907 $10 Indian Satin finish Proof-67 NGC has been auctioned off on the 5th of this month. What a nice coin..... http://coins.ha.com/common/view_item.php?Sale_No=1151&Lot_No=5238&ic=rightcolumn-1907result-010711
2 million is High I agree that is crazy money. but the Satin Proof mintage numbers for 1907 $10 Indian is what made this price go crazy http://www.usrarecoininvestments.com/coin_info/proof_eagles.htm
I don't think it was an inflated price at all, the story is absolutely AMAZING and there are less than 40 known and that number could be as few as 10 or less. And it is believed to possibly be some type of presentation piece. I think it's a very unique coin and in person it is beautiful! -Russ
