You have already been offered 1.1 - 1.2 and you are holding out for 1.3 on an MS64? For 1.3 you can get an MS68 2011-S2. Regardless GLWS.
Thanks for the interest, 1.3
BTC is my absolute lowest price.
I've helped broker deals on SEVERAL Casascius coins in the last 30 days.... 1.25
BTC for MS68s that came fresh out of a roll were the highest sale prices. The brass have ranged anywhere between 1.1-1.25
BTC. Unfortunately your coin is worth 1.1-1.125
BTC at this point in time. This coin will not sell here for "your" price. It's an MS64 in the newest ANACS slab..... best of luck.
