This very nice chip has been sitting around in my spare's box for many years. Perhaps, someone might have a clue about it's identity. It's a well-made chip with denominations (25-Cents) around the rim and four on both sides -- face and reverse. Both sides have what look like a machine gear, a pair of African Palm limbs, the word Poker and four white spades on both sides. The chip is very smooth and it sounds like a Chipco satin when it hits a hard table. I am guessing it is a home game, but can't find any samples like it. Any help will be appreciated. I can put it up for consideration in the ChipGuide, but am totally lost. It surely is part of a set of extremely fine chips. I found it in one dealer's big barrel of chips for $1. Really nice. Thanks for any help.
