German states of some sort? Edit... correct above. According to ngc world coin guide, worth about $1.50.
OK - to start with, you have two lions on either side of a shield. The most clear lion runs from about the 2 o'clock position down to the 5 o'clock position; three of his legs touch the shield, and the fourth leg rests on the heavy horizontal bar. The other lion, opposite, is a little harder to make out. The shield (or escutcheon) is divided by a diagonal line, from top left to bottom right. The coin is probably a fairly low denomination, made out of billon, an alloy of mostly bronze/copper plus a little silver. If it were 60% or 80% or 90% silver, it would not be so corroded. I don't see the 1789 date, where is it? This diagram (not intended to represent your coin, just a sample) will help you see what I'm seeing:
Here is the coat of arms of Utrecht, looks similar, but the lions' feet are different, and the shield is a different shape. The coin's design is clearly the coat of arms of some city, province, or other political subdivision, and I would lean toward Germanic too. edit//hard to say if the Utrecht design has changed significantly over 200+ years - don't know.
Or you could just google "Utrecht duit" https://www.google.com/search?q=utr...en%2Fdetail%2Fstad-utrecht.-duit-1788;575;565
Everything you could possibly want to know about duiten from Utrecht: http://www.duiten.nl/utrecht.html It's in Dutch, but you will get the general lines, and all the different types are illustrated with line drawings.
