I must have 500 to 700 distinct (not counting different colors of the same chip) crest and seals, seal and crests, or inlaid lithos. I only have one such chip with edge spots.

The chip below is an early Burt chip. I figure it's a Burt chip due to the edge spots (which Burt introduced). Due to its similar construction, I think it was made at the time of the early Dunes and Flamingo seal and crests.

Can anyone identify the chip? Also, is there another example of a seal and crest with edge spots? Lastly, does anyone else have this chip?
