Cant Sell Coin of Luck to Buy Shops

[Tourman 0]

Just went around thru 3 towns and over 10 buy shops. Restarted client multiple times. I have Coins of Luck in my inventory but cannot sell to any buy shops. It is greyed out like I do not have any in my inventory.

I can confirm.

But those prices are a steal so don't sell.
