I like 'em, would advise you also make a 25 cent chip just in case.....
I like them as well, but what about adding a watermark to the inlay? Watermarks scream classy and add a layer of depth.
Love the mockups! This is exactly the type of inlay design I would like to use for a custom or semi-custom set.
Another reason to make a rack of quarters or even NCV's...ups resale value considerably! I know you won't use them but you never know when you might sell for a different set and these are not personalized so they would have good resale value.
