I don't want any issues with having two auctions going on the same coin because I don't think it is fair for the bidders so here goes. On ebay I have posted a 2013 Casascius 1 BTC silver coin with gold rim as an auction. The current bid is at $8,400 at the time I am making this post, if you want to bid you need to follow the ebay link for fairness, but I will accept BIN offers here in fiat, tracking and shipping should be included in whatever price you offer.

So you will accept a bin price in here and accept fiat using ebay to get buyer protection?
If you accept bitcoin and use escrow here you will get more interest here as most people in here don't deal with fiat as much as crypto sales...
