Stuck on one of last coins of 3700-coin lot [решено]

For the past few months I have been identifying the 3700 coins I bought, mostly modern and mostly low value, low denomination common coins. One of the last 50 coins is real problematic due to poor condition. One side is a coat of arms and Latin legend, the other is possibly a single word across the middle.

I spent a few hours looking at coats of arms entries in Numista Catalogue with no luck. Any help or information anyone can provide will be very welcome.

Coin is paper thin, weighs 0.64 g and is 14.4 mm in diameter. Seems to be copper or bronze.


Thanks for your assistance.

Thanks so much for your help, guys! I am sure now that it is Krause C# 40 of Tuscany, known as Kingdom of Etruria at time (Rex Etr on coin). Squinting real hard I see date 1803 or possibly 1805 on coin under quattrino. Too bad it is in such awful shape.
