I have several different inlay-roulette type chips that have etched or hot stamped initials on them. Thus far, I have not found a home for them.Since they are generic (as is your litho ship chip) if used in a club, that would explain the addition of an initial - to prevent someone from bringing in a chip of the same kind. TGT, 3rd does not list this chip as being from any club as you probably know.
