Jim, The "cute" heart design is the Lady Luck logo that you will find on other much earlier Lady Luck chips. Sometimes even with a face in the middle. Since it should stand to reason the casino would want their logo to be the promenate part of the chip, I would consider the heart design side of the Millennium chips to be the "obverse". But of course that is only my personal opinion and remember I liked the "wrong" side of the tiger chip!!! Janice
