My thanks to all - esp. Rick for helping me clear up my Harrah's strike confusion.

Today I found two 1993 Sam Boyd - Sam's Town commemorative pieces. I guess these are not "strikes" (although they look like strikes and are housed in the same kind of direct AirTite cases as strikes...)

There is no denomination on these pieces.
They are the same size (diameter) as my $20 AC Dolphin strike - although their weight in grams [Sam weighs in at 73.5 in case] v. [$20 AC Dolphin at 63.5 in case] is heftier.

I have 2 of these... and would like to know if anyone is interested in having them. If yes - please email me... will gladly trade for Harrah's strikes I do not have (or that I do not have coming).
Thanks again all for your patience/ help and trades!!
