Here are six words that end in LLIERIES:
Coilliers, Dalliers, Milliers, Ralliers, Salliers and Talliers.
Then again, that word may be part of a person's name--or a name made up by the owner.
If no responses to your initial question, you may wish to do a little more cleaning to bring out other letters.

The value will depend, in part, on the name (and history) of the company we are trying to uncover/disclose.
I did see one Insurance Credit System token go for a couple of bucks.

The token is listed in the newest Edkin's Coal Catalog book. yours is the nickel plated example KY385A100a, with an R-2 rarity rating, from 1 to 10. 10 being the rarest. it is from Brookside, KY., Harlan County.
that is a crossed pick & shovel on the obverse. other denominations known, from the same mine, with same wording, go from 5¢, 10, 25, 50 & $100. no penny has been located...may never had been one made, each company had custom orders from various die makers.
there is another full set with a different die maker's reverse from Orco.
I remember seeing a few stacks of this companies tokens, with the crossed pick & shovel, on the TV show Pawn Stars, in the last year or two.
