..if there are no chips known on it.
There is one for sure, looks like a sample chip for the San Francisco Card Co.
The records exist. She won't sell them yet but sooner or later she will.

"..if there are no chips known on it."
I think we said that when the Yorkshire Incused Rectangle mold showed up a few years ago.
I've seen lots of different chips on the mold since then.
I think I like "Braids" the best.
BTW, it is a clay chip isn't it?
