Unknown coin just found in the garden. [επιλυμένο]

Does anyone recognize it?

The green color makes me think of a copper alloy.

Ruler in centimeters for scale.

I should have the weight by tomorrow as well.

Thanks for any help.

Maybe this?   N#18634

 I did turn the first picture over and see 1760 date so yes could be that.  

Or this: N#15634

Or this: N#15634

 

Probably not, because there is no space between 17 and 60. (TNK)

Thankyou!

 Thanks. This is what I was going to add but then saw the 

reply after me had made similar … 

 But yes it is that Austrian Empire coin

EIN  KREUTZER  1760 H 

They are both Austrian Empire coins, ein kreutzer 1760 H. One from Maria Theresia, one from Francis I. The lettering on the obverse is totally different but unfortunately nothing of the lettering is readable.

But I'm pretty sure it's the one from Maria Theresia, for two reasons:

- The EIN on the Maria Theresia coin is straight, just like yours, and the EIN on the Francis I coin is bowed.

- Because of possible varieties, which happened a lot in that time period, there's a chance the first reason is not sufficient enough. But although nothing on the lettering on the obverse is readable the contour of the bust is visible. And look at the shape of the contour of the bottom and especially at the shape and the placement of the notch. Your coin can only be the Maria Theresia one:

 Excellent. Thanks ! 

Problem: there's a third 1 kreuzer 1760H Maria Theresia, from the county of Tyrol (N#491969). 

It has practically the same obverse as the other Maria Theresia kreuzer but can we rule this out because of the shape of the “1” in the date (the “1” isn't clearly visible on OP's coin)?
