THIS IS A FANTASTIC  AND PRETTY RARE ITEM FROM THE CHAMPAGNE HOUSE OF BOLLINGER. IT IS FOR A SINGLE CASINO CHIP. THE CHIP HAS THE BOLLINGER SHIELD PRINTED ON THE TOP. I WAS TOLD THAT THEY WERE PRODUCED TO PROMOTE THE JAMES BOND FILM CASINO ROYALE BUT I DON'T KNOW IF THIS IS THE CASE . I DO KNOW THAT THEY PRODUCED BOLLINGER CASINO ROYALE KEYRINGS AT THE TIME SO IT IS POSSIBLE. EACH CHIP HAS A DIAMETER OF 1  1/2". PRETTY RARE AND UNUSUAL ITEM FOR ALL YOU CHAMPAGNE/BOLLINGER/GAMBLING/007 JAMES BOND COLLECTORS OUT THERE. MADE FROM METAL.
