Tips:
1) Stay away from China. Anything of unknown origin and/or odd markings is not worth the risk. Just save yourself the hassle and do not buy it.
2) Buy as close to pure as possible. The lower the silver content, the higher the refining charges. Staying above 90% purity will ensure the highest payouts.
3) Figure out a way to test things before you buy them, or a way to verify them upon delivery (as if you purchased from eBay)
4) Figure out your percentages first. Don't do it on the fly. Find a refiner (
) and then work their rates backwards so that you already know what they will pay you for what you are about to buy. Then work in the amount of profit that you want to make and that either gives you an offer price, or a max bid price.
5) Don't forget to consider the hidden costs... transportation, shipping, time, packaging, provision for loss on ignition, and any other pennies that will add up to dollars in the long run.
6) Get a good scale- one that is portable and can weigh up to 3000 grams. I use 2... a pocket sized scale for smaller pieces, and a larger one that fits into a laptop bag in which I carry other stuff, including personal protection.
7) Don't be afraid to walk away from a deal. If it's not on your terms, then don't even begin to bargain.
8) Ask where things have come from. You don't want to accept anything that has been stolen.
Consider that MH will pay you 85% on sterling. There is a $25 assay fee if I buy it directly, but I waive that assay fee if you get refined metal in return. You also have to ship it to me at your expense. So you're looking at $30 cost, and then I pay 85% of the fine metal contained in your lot. Let's assume that you bought 100 troy ounces of sterling silverware...
That would be: 100 x .925 x .85 = 78.625 x silver price (let's use $27)... I would pay you $2097.87 for your 100 ozt of sterling. So, at $27 silver, your favorite refiner will pay you about $20.97 per troy ounce of sterling. If you want to make an additional 10%, then your offer price or max bid price would be $18.87 per troy ounce of sterling. $18.87 divided by SPOT will give you a good multiplier to use for future purchases...
So... 18.87 / 27= .69888888888
This means you can safely use
spot price X .7 to estimate a price per troy ounce of sterling that you can pay and still make 10% on 100 troy ounces.
