Amazing nobody has even guessed.... IMHO from $3,900 to $4,400, I figure. Folks are reluctant to sell, that makes prices a tad higher than advertised by just the melt content. Also, 2010 had a unique laser etched frosted surface which was either (A) the best thing since peanut butter, or (B) the ugliest thing ever produced by the mint. I do know it's a key because of that finish, as it is supposed to be changed in 2011. So sell away, but replacing the set in even 30 measly days may be hurtful to your psyche. What a price rise this is.
