BEING A NEWBEE AND JUST GETTING MY FEET WET (THANKS FOR ALL THE HELP, YOU GUYS/GALS ANSWER FAST WITH GREAT INFORMATION!)

I AM LOOKING FOR A WEBSITE WITH THE CURRENT VALUE OF THESE CHIPS- I HAVE THIS TROPICANA 1994 TCR4506 $5. THE BOOK I HAVE DOESNT EVEN MENTION THESE CHIPS- THEY ARE RIGHT OFF THE TABLES AND NOT THE ONES PEOPLE MAKE-
ALSO A GEORGE BURNS $5 100TH BIRTHDAY AT CAESARS
PLUS THE COIN TOKENS- WHY ARENT THEY VALUABLE? DIDNT THEY MELT THOSE DOWN? THANKS, WEST
