Swiss 1/2 Taler Zurich "REIPUBLICAE TIGURINAE MONETA" 1768 [решено]

Hi everybody,

my beloved wife has bought a bundle of old silver jewelery, rings, brooches, necklaces etc.
One necklace has a coin as pendant.




Written on the front side is "REIPUBLICAE TIGURINAE MONETA" 1/2
the backside says : "TIGURUM" "1768"

weight : 13,88 gr (including eyelet)
diameter : 33 - 33,5 mm

Material seems to be silver (she bought it as well as silver from a trustworthy dealer). Its antimagnetic - the ping test indicates silver to me - also the magnetic slide test with a small neodym-magnet, but thats just my opinion.

At first I thought the coin on this necklace might be an Exonumia medal, but Google surprised me.
It seems to be a coin:

Here are my questions :

1. Is it this coin ?
2. Is it real or fake ?
3. How does the eyelet reduce the value of a coin ?
4. Is anyone interested in this coin ? I would like to swap, but i am open for suggestions.

Best regards

Hello,

To answer your questions as best I can:

1. This is the coin on Numista:

2. Can't say for sure, but perhaps more focused pictures would help.

3. It's not as unsightly as some other solder vestiges I've seen; by the looks of it only the rim is affected, so as a conservative figure, maybe 5-10% of value lost? Not too much, but less valuable than the same coin without it altogether.
