..history of your chips, collecting illegals can be the most satisfying sub collection in the hobby.
Most are not expensive chips.
I have over 2,000 Ided illegals, 243 from the KY illegals.
Most are rich in history.
They flourished from the end of proibition in 1933 thru 1961 all over the USA. No one knows how many existed but it is in the high 1,000's. We find new ones every day.
Here is our site with over 15,000 old manufactures records on it. Hopefully 15,000 more coming soon.

That would make over 30,000 know records. Not all records are for the illegals. If half are, that puts the number of known illegals at 15,000.
