I have a fully funded 2011 single-error Casascius physical brass Bitcoin. It has been in a coin sleeve since I purchased it as a gift at a festival back in 2012.

ANACS is no longer grading these so I haven't been able to get it graded. Slight tarnishing/patina on the non-hologram side.

Fully funded with 1BTC, 1BCH, and all other relevant alts.

I'll figure out an intermediary with the buyer when the auction ends. Auction will be open for exactly 1 week starting when this post goes up and starts at 1.2BTC.

Happy to take additional pictures/ answer questions.
