I've added the follwing items:

.50, $1, $5 defaced Jenna Chips from the Sands Casino, Black River Falls, WI. These were first defaced at the Ho Chunk Bingo & Casino in Baraboo when the tribe terminated their management contract with Jenna Corp. They actually paid someone to scratch the name "Jenna Corp." off each and every chip.

$1 LCV from the President, Davenport, IA

$2.50 H&C from the Empress, Joliet, IL
