I do not know where they are from, but the guy i bought them from said he got them in Nevada City, Ca.(estate sale)
Not sure why a black "X" is painted on the back.

the PC chip (w/2 kings) is Patio Club........Petaluma,Ca
the GH (green lgcrown) is the Owl Club....Bakersfield,Ca
the CR (blue diamond Square) ??
the Logger Club (red L's) very light overstamp in ink...says "SILVER DOLLAR"
Any ID help with these is greatly appreciated. I can get a few more of the ERC $1blue and $25 purple (if he didn't sell them all at the faire) I can also get more of the Logger Club chip. I have 2 sets of the ERC..one for me and one for our friend..Dennis Berry. He only had the 2 green.. I bought them both.
