OK, I'll admit that dealing with these private issue insulators isn't my forte, so either they are not very popular or my prices are too high? I'll assume it's my pricing and make this final blow out reduction:

Here are some Mid Ohio private issues in the CD 317 style. I am offering them at $15 each***NOW SALE PRICED AT $10 EACH*** (except the solid pour @ $20***NOW AT $15***, bottom left), plus shipping & optional insurance. Buy five or more and I'll split shipping costs with you. Swirled ones are washed out and darkened in the pic and are much more colorful in person.

Those SOLD, left to right, starting top left as number one: 1, 3, 4, 8 & 10. Others withdrawn.
