Hi,
Welcome to JustAnswer.com, I am a verified expert and will be working with you today.

I assume that these are sterling silver? Can you tell if there is any information on the weight of each piece and the silver content?

Customer: replied 4 years ago.

THE WEIGHT OF THESE ARE 60G THEY ARE STERLING SILVER, HOWEVER AM UNAWARE OF THE SILVER CONTENT, PLEASE DO NOT REPLY IF THIS WIL COST ME ANY FURTHER MONEY AS HAVE ALRADY PAID £29 FOR THIS RESPONSE WHICH I FEEL IS EXCESSIVE & UNSATISFACTORY

Expert:  Wayne replied 4 years ago.

I don't receive any money until you accept my answer. The amount of money is a deposit. They're really not worth much more than the silver value, as these are not coins, they are medallions made for collectors, sold by a promoter for about 10x the silver market at the time. If you search Franklin Mint you will see very similar things selling for silver value or just over. As you said these weigh 60 grams. Here is the math 1 troy oz weighs 31.1 so 60/31.1= 1.92 Troy oz each. Pure silver is £21.7 per oz. These are sterling which is.925, £21.7x .925= £20.07 an oz x 1.92oz = £38.53 each. x 16 pieces is £616.48 silver value . The most these sell for is 10% over this value being £678.12.
