Guernsey Coin [решено]

Hi all
I just got this coin, that says, and looks like it's from Guernsey, but I find strange that it's not on the catalog, and Google searches throw little or none helpful results.

Can anyone give me a little more data on this? Was I scammed?

Thanks in advance.

Hello , some are on eBay for sale too.
