One of the interesting tidbits of trivia about him is that Japanese writer Haruki Murakami has credited seeing Hilton hit a double at Jingu Stadium as the inspiration for him to become a novelist.
Hilton's 1973 Topps rookie card also has Ron Cey and Hall Of Famer Mike Schmidt on it so it's a bit pricey.
Hilton's NPB cards aren't quite as valuable. He had a number of cards in the Takara, Calbee and Yamakatsu sets from when he was in Japan although most of his cards appear to be from 1979. TradingCardDB only lists Takara cards for him for 1978 and 1980 although the 1978 Calbee set is poorly checklisted and it wouldn't surprise me to discover that he has a couple 1978 Calbee cards. The only cards I have for him in this time period are his TCMA card and Yamakatsu card:
|1979 TCMA #18|
|1979 Yamakatsu JY8 #16|
|2009 BBM Yakult 40th Anniversary #42|
|2013 BBM Deep Impact #05|
