I just aquired 4 $20 A.C. Harrah's 15th aniversary Strikes and wanted to get info and the value on them if anyone could help. #1 is Absecon Lighthouse, # 2 is Great shearwater ( bird), #3 is a bottlenose dolphin, and #4 is mid atlantic regatta, ( Sailboat ). the reverse on all of them says Harrah's with a large 15 and aniversary. 1980-1995. Thanks, Frank
