The listing, 2006 and 2007 US Mint Proof Sets has ended.
Up for auction is not one, not TWO United States Mint Proof Sets from 2006 and 2007. The US Mint website explains them better than I do, so let me quote:
The 2006 and sets contains 10 and 14 coins respectively "in proof quality, protectively encased in three clear plastic lenses and newly designed packaging. United States Mint proof coins feature sharp relief and a mirror-like background. Their frosted, sculpted foregrounds give them a special cameo effect. Proof blanks are specially treated, polished and cleaned to ensure high quality strikes. The blanks are then fed into presses fitted with specially polished dies and struck at least twice to ensure sharp relief. The coins are then packaged in a protective lens to showcase and maintain their exceptional finish."
I will even provide free priority shipping and will do my best to ship them ASAP (see my previous auctions to attest to my fast shipping).
Finally, I have provided a GIN for those who can't wait. Good luck and happy bidding!
Also up for bid in a separate auction is the 2002, 2003, and 2004 US Mint Proof Sets:
