I have seen these for sale for 13 USD. A better answer as to what they are worth is their silver value. The weigh 23.3 grams and are 50% silver so they contain .375 ounces of silver. At the current silver spot price of just under 18 USD that would make it worth about 6.75 USD.
Dates are needed, post new question.
13 kilograms is equal to 13000 grams.
8USD 87cents as of 3/23/13
its about 18 per gram for 14k and about 12 per gram for 10k
Id say that 13 grams of gold is worth a lot of money i'm no expert but its worth at least 100$ but i'd say it could be worth like 1,000 dollars take my word for it if you sell it its bound to be a lot of money so if you have gold i wold totally sell it take my words.
If there are 10 peices included then it is worth $23. If there are only 5 peices then it is worth $13. If it is a 10 peice 90% silver set then it is worth $120.
As of today 9-13-11 it's worth about $40.00.
Approximately 13 grams.
13,000 grams. or 13,000,000milligrams
