Unspendable prize wheel coin?

I When I first started playing, I got a prize wheel coin from zeki. The description says "use at zeki's prize wheel in the underground ".

Since then I've gotten several two prize wheel coins that I've had no problem using at the wheel, but it won't take this one. the wheel gives me an error "required an item : 2 prize wheel coin".

This one prize wheel coin also doesn't work at the market.

Should I just sell it? Has anyone else been stuck with this coin since day one?

"thrilling" update!

I finally got rid of it! I didn't realize I always had an odd number bc I always won at hotpot. I just lost and got one coin to match my sad single coin!!

I got 10 unopened oyster lol. But I did get one green pearl!

And the day is saved
