I collect error chips.
This is not an error that would add much if any value as there are very few error collectors.
I keep this type errors but would not pay over dace for it.
There is a difference between off center errors and real errors.

I sold an error $5 chip from a strip casino last year, it was on a different strip casino house mold. I think I got $1,500 for it. There is 1 more like it on the tables. I have several poker dealers looking for it.
