09-28-2010....The US Mint has ceased minting 50 dollar proof buffalo gold, and has run out of blanks. They will produce no more this year. Final mintages are in the 30,000 to 35,000 range, according to NN Stats this morning. Ebay has some BIN as of 12:55 Eastern Standard Time, with a few lots of multiple coins, up to ten. This is a sure winner.
