US Rare Coin and Currency offers expert assaying services to customers who want to determine the types and quantities of different metals in an item. We use state-of-the art x-ray fluorescence analysis to determine the metal type (i.e. assaying) and percent of total.
We can identify elements of 26 different metals, including gold, silver, platinum, palladium, copper, zinc, nickel, cadmium, iron, manganese, and lead among many others. Whether you are a silver or gold buyer or seller, want to understand the value of some gold jewelry, or are trying to identify or validate the content of items you have found or had manufactured, US Rare Coin and Currency can provide an accurate assessment of the metal content. We can not assay rocks that you may believe contain precious metals unless there are visible and larger sections containing metal.
If you would like cadmium or lead testing, our x-ray fluorescence testing is the same method/technology that many state agencies use to test toys and other items for lead or cadmium. However, we are not a licensed cadmium or lead tester and cannot provide official documentation.

Specific gravity (density) can be a good secondary way of supporting the output of the x-ray fluorescence analysis. We can provide specific gravity testing any metal objects and the output will be the average density of the metals used to make the object. Limitations on the test are for objects that are hollow. We provide specific gravity tests only on items that have already been submitted to x-ray fluorescence testing. This test can indicate what an item is not (with a reasonable degree of certainty) but not the contrary.
Applicable once XRF testing has been completed.

Testing items that have at least two flat, parallel sides can be another way to determine what metal an item may contain. We can offer ultrasonic testing on objects that have already been submitted for x-ray fluorescence testing to determine if the material found during x-ray fluorescence is the same which may be deep inside the item. Typically, this is only helpful in negative identification and when the item is suspected of being pure. This test can indicate what an item is not (with a reasonable degree of certainty) but not the contrary.
Applicable once XRF testing has been completed.

We can also provide written documentation of the results on all of our testing. This documentation comes written on our letterhead and can, if needed, include a picture of the item tested.
