The weight is more off than the wear suggests, but otherwise, it looks good to me (that would be Y24, not Y 25.) Did you do a ping test and inspect the edge? If it pings correctly and there's no seam, it is hard to think of a method to get it so right...

I gently dropped it on a glass table and it sounds nice to me  ::)
There are some odd areas on the edge, particularly at 12 o'clock (possibly a mounting mark?) but no seam.  The stars do not seem to be at equal distances.

The wear is not significant enough to suggest mounting, unless the jewellery was almost never worn. The irregular stars don't worry me. At the turn of the century, collars were still hard to make.

Next thing I can think of is visit a friendly jeweller, tell him it's supposed to be .800 silver and ask him if the colour is right. If he says yes, I would say it's an underweight error of a genuine coin.

The colour reminds me of the fake George V florins and half crowns which were cast in zinc.

Yes! If this colour would be Ag 800, Tim needs a new scanner.  ;)

Famed as I am for my scans and scanner, I have to say that this is an accurate digital representation of the object in question  :o
And I'd have to concur.  I don't think it's silver.
However, I've just done the 'rub the edge on a piece of white paper' test and compared with a 50% silver sixpence the results are strikingly similar but slightly less pronounced.
I also tried to work out the rough specific gravity of the piece.  The depth being approximately 1.8mm. Let's not go into it :-[

It looks like zinc.   Probably plated or washed if the coiner was serious.   Although fresh and lustrous zinc is pretty close to the color of silver.   Specific gravity is 7.1 versus 10.5 for silver.   That can be boosted by adding lead, but that makes the natural luster go dull faster, and silvering more difficult.

You can get the same colour by keeping it in a white paper enveloppe made of chloride-bleached paper, by keeping it in plastic with softener or even keeping it in one of those dusty antique shop with a faint smell of decay that gets into your hair and clothes if you stay there too long. That doesn't mean it's not tin, just not automatically so because of the colour.
