Someone on the BB posted interest in encased cents awhile ago.
Don't recall who it was. Anyway...
The latest "Casino Collectibles" (Dean & Jodi) monthly auction sheet includes 6 casino-related encased cents:
Joe W. Brown's Horseshoe Club
Las Vegas Club
Horseshoe H&C Las Vegas
Gold Club - Sparks
Harolds Club Reno
Bright Spot - Reno

If you need to get in touch with them, email me for their contact info.
