Sorry, I can't help, Albert. I have added them to TGT-3 data base
as unknowns with your name as the reference. All 3 look like casino
or club chips, not for private use. No problem with the BOB or WGA,
but the other one is a little difficult to define. I believe it is
822, rather than B22 or B2Z. It was a common practice to shape the
letters or numerals to form a circle, oval, diamond or any geometrical
shape, in this case, a semi-circle. It seems more logical that it is
part of the illegal clubs address, 822.
