Here is a list and pictures of those I have for sale (just the litho inlays on the list are Crest and Seals).

If you can't download this page, please let me know:

I buy, sell and trade these special-order inlay chips (crest and seal, and plain monogram inlays).

Incidentally, I think the best definition of Crest and Seal chip is: clay chip with litho inlay (not the plain, die-cut silhouette-type inlays) and a flat/plain mold (not the embossed distributor rim molds, such as hub, greek key, etc.).
