I truly hope you don't believe someone will pay you extra 1btc for the brass coin itself. That's not happening.
I think I made it clear what I believe this can fetch, If you can or don't want to pay it it's up to you.
I think it's pretty clear you understand the value otherwise you wouldn't just jumped in to try and get it unpeeled
And using minerjones as escrow is already 0 risk. But i don't blame you for being newbie and looking for unrealistic prices and ignoring the minerjones escrow request.
Maybe low risk but just having a trusted escrow is not a guarantee here, maybe if he picks the coin in person, which doesn't make sense with the price mark you suggesting
With your price request looks like you're looking more for a scammer that will say anything you want to hear instead of legitimate buyer.
Good luck with your sale
The best way to get scammed is to DM someone who doesn't provide any meaningful details instead communicating in an open thread.
Also I wasn't looking for a seller just trying to understand how one would go about selling property with such high value which I would still love to get an answer for if anyone here got to do any trades for such value before
