Been a collector and hobbyist since I was a kid and have collected everything from stamps & coins. and other small collectibles such as matchcovers,swizzle sticks,antique bottles,postcards and dog licenses etc. and then progressed early advertising items,old calendars, art nouveau lamps,bakelite boxes,radios,records,Asian art,antique cigarette holders,antique snuff bottles,netsukes,art deco furniture and Italian art glass. The list goes on. The lsit went on so long that I actually started a collectibles business.
Went to the Hard Rock in Vegas in January of 2007 and saw a chip display at the cage and struck up a conversation with the cashier who recommended Halloween chips as they came out every year.Bought a couple and then went to other casinos looking for same. THAT WAS THAT! Boom...I was hooked.
I like them because there are new ones coming out all of the time but have branched out into older more GRAPHICALLY PLEASING ones as well.
I like them old or new as long as they have a high GP(see above) factor.
