Did the OP miss out on our vibrant community over at the "Collectibles" section? I may have come across many Casascius coins auctions running there from time to time. I dont regular that section but it is pretty active and filled with the OG coin collectors of this forum.
Rather than going to eBay, you can set up a trade here with an escrow with minimal fees.
The main issue now on buying online a cas coin is the shipping process most importantly if the seller and buyer are both from different country. It’s very hard to entrust cas coin loaded with 69K$ which the value is not declared on the shipping company since it’s mark as collectible only.
I preferred selling the coin IRL rather than entrust it to a courier which we don’t if they will deliver the item safely.
@minerjones, do you still manage to ship successfully loaded casascius coin with the current value of Bitcoin?
Agreed, IRL transfers are preferred due to the current value.
Logistically speaking, shipping a coin of this value no longer makes sense... no insurance will cover the digital value nor would I want to have to declare that amount on a customs form.
The escrow could act as the courier if needed
I do still have people who want to ship the coin due to location, but am recommending at this point to either peel and redeem the coin or wait for an opportunity to do an in-person transfer
