There are two different chips that fit this description, Miles.

One of them has a picture of a Saxophone player (pictured below at left) and has the small greek key mold. It is rated as a $60 - $74 chip, and in decent condition this chip has been going in the $45 to $75 range lately and is the more common of the two.

The other chip, also black with lavender inserts (pictured on the right) does not have the sax player and has the Cristy and Jones version of the hat and cane mold. Although rated lower than the previous one ($50 - $59), it is seen far less often and generally sells in the $50 - $75 range.

IMHO, both of these are beautiful chips.
