Ioseph II 1786 Coin, Poss Austrian ?

Hello Mike and welcome to the forum!
Joseph II was the ruler of Austria, and the M most likely stands for Milan's mintmark. I didn't find anything fitting the description in Milan though. As pls mentioned the picture would be the best help in identification. Otherwise as much info as you could supply. The size, the weight (if you can determine that), composition (copper, silver, ...), all that would help with ID.

Think this is a better attempt at the reverse off the coin.

This thing is driving me crazy!
The coin looks exactly as I had pictured it in my mind, but for a long time I couldn't find it even though I looked through the whole (I hope) empire and its possessions. Until I looked at higher denominations. Did you fail to mention that the coin was gold? I kinda doubt it.

So, here's the scoop. The design matches 2 ducat coin. But, first of all, it should be gold, second, a wrong mintmark, should be A, B, or E. Unless I'm missing any Austrian territory I believe you have an imitation 2 ducat.

Please someone correct me!
