The prices that you are setting based on the price of silver, may be too high if the person is planning to melt it down.
The refineries have higher fees than they do for gold, as it takes such a large amount of silver to be worth melting down a batch, compared to gold.
I haven't evaluated your prices closely, but it's something to keep in mind.
If the prices are too high, than it is likely that the people winning the bid are speculating on the price of silver, hoping that it will go higher and they can make some money on the silver in the future.
Thank you, that is interesting to know. Clearly they have stopped speculating. I will bear that in mind in future pricing.
