How much is a 925 silver chain worth?

It depends whether it’s 925 parts out of 1000 parts from Germany between 18 そして 1900 where there is no numbers there are pictures of swords animals and even two crabs holding hands. These pictures are so tiny that a standard loop you can’t even see them but someone that knows what they’re looking for can see them without identifying what the picture is at that point without a really good scope that more than likely that would be silver (no plate). Or it’s your local Michael Hill jeweller 925. Say your chain is 20 g in week at the local silver merchant he’ll give you 10 bucks if you lucky. However if you got the picture of the two crabs and stick it on eBay you probably squeeze $100 . If you think you have something special that you know is old your best bet is to go to your local auctioneer and he may get you more because I think there are people that chase certain hallmarks Annie can lead you in the right direction.
