It's a "steel cent" as we were using the majority of brass & copper for manufacturing armaments'

If you can find a 1943 Lincoln cent that is Bronze, BN Regular Strike (95% Copper, 5% Tin and Zinc) Lincoln cent , your in the chips-- about a million chips!

Interesting, Ari.

It is probably valuable. My guess: $100 US dollars, maybe more, to a token collector. But that's just a guess. It's a rare piece.

The front is a well known FOR PUBLIC ACCOMMODATION Civil War Token. But you rarely see these without a small eagle on the reverse, as shown here:

However, instead of the small eagle, the FOR PUBLIC ACCOMMODATION obverse was sometimes paired with merchant "store card" reverses, like the one shown in my first picture from PCGS.

Like you, I could not find one paired with CATHERINE MARKET, but, tokencatalog.com yielded a CATHERINE MARKET pattern identical to yours (second picture).

So, you have a token with a Civil War Token obverse and a "store card" reverse. It is probably quite rare. Keep it safe.

DO NOT CLEAN YOUR TOKEN. CLEANING RUINS VALUE
