Both WRB chips found in Yerrington, Nv

Colony $25, BEB $1.00 , PA $1.00 and CC 5 chips all found with some other old Zig-Zag mold Nv chips..ie: Mt Charelston Lodge $1 and a 1st issue Tahoe Biltmore $25 green.
The CC chip is intresting in that the hot stamp on both sides of this rectangles mold chip is so primitive in it's appearance...Any ideas?
Thanks for looking
