...in The Chip Rack are, as Bob said in his inimitable way, the purple/green dovetails from The Mint, listed as E7222 for the one with the green tail and N2750 for the one with the purple tail.

Another one in the same ballpark is the Harold's Club pink web mold chip, listed as N9866.

That said, I personally consider the Reno Horseshoe that Charles shows as one of, if not the best looking $2.50 chips.
