How To Determine Approx Date Of A Token?

I have a copper token that is the size of a modern cent.

It has a business name and location on it, but no date.
I always assumed it was a late 19th early 20th century
'business card' token.

I took it to a dealer once though, just to get a better idea,
and he told me it was an early 19th century "hard times" token.
That's cool and all, but why would a token from that early
be sized like a cent from 40+ years later?

I know little to nothing about tokens, business coinage,
and business card coins, but would not the tokens from the
1820s "hard times" be sized like the cent or 1/2 cent of the time?

Thanks for your input.

Sorry no pix.
The coin is stored away.

It is sized as noted above.
