This coin is a tax token from one of the Illinois Counties. The state issues were far more common, but Illinois & Washington State had many different county issuers.
Obverse legend reads “Redeemable in Pekin, Illinois / Association Of Commerce” in 2 concentric circles clockwise from 7:00 to 5:00. The denomination of “1/4 c” is in the center. A diamond shape is at 6:00.
The reverse has the legend “Tazewell County Token” clockwise from 7:00 to 5:00 around the same denomination. A diamond shape is at 6:00.
Identification code: L97 (there are L97a through L97f varieties – I don’t know what differentiates them… yet!)
Mint Mark: n/a
Mintage: unknown (although this is listed as a relatively common R1-R3 token)
Country of origin: United States

Estimated Value: $3-15 (I found 2 that sold on eBay: an AU one that went for $8 and one in roughly the same shape as this one that sold for $16)
