I found this in a recent bag o coins. The date is led-gable and it is 1765 ( I think ). I cannot read very much of the writing ?heres.d.g? g.bo.reg. composition: copper diameter: 21mm weight: aprox. 1.48gm
It is a coin from the Austrian empire, an issue of maria Theresia. Likely a 1 Kreuzer.
By the way, it was helpful to have the partially deciphered inscription.
Unfortunately my older krause from the period is not well organized for searching the different mints and states (they did not all use uniform designs), and is missing many illustrations of the minor coins, so I can't narrow it down further.
Someone with more up to date information could probably help more, or perhaps you could search numista.
