Last sale was a few days ago for US$1,350. Found info pretty easy- 600 mintage. 115m in diameter, 20mm thick. Weighs about 4kg incl display. Trivia for the day- Moby only appears in the final 3 of the 135 chapters. That's a lot of reading for very little Dick

So slow Looking at it again, the listing was 'ended' so not sure if that's the actual sale price or a hopeful seller. AU$900/kg for a small mintage huge ass coin sounds about right though. Looking to buy one?
