Hi,
My wife has had these cups for awhile, and we were wondering if any info could be made of them.
We have a total of 12.
They do not have any marking/stamps on them
We did take one of the cups, and filed about 1mm into the bottom edeg of the cup. It appears to be solid silver (at least not copper)
The cups are 4 inches tall, and 1 3/4inch wide
Also, how can we tell the grade of silver, sterling or not? Are there reputable places that we could send one into for testing?
any info would be appreciated
thanks
