Start by buying from experienced sellers that have an established reputation for selling such things and getting positive feedback from actual users over a long period of time. Avoid new or inexperienced sellers that may not know what they are doing or that may be getting their stock from dodgy sources, or sellers that have drastically changed selling behavior recently.
Having a known-good specimen to compare your new purchases to is helpful. Calipers and accurate digital scales are inexpensive.
It also helps if you have a relationship with a local coin shop that may allow you to verify precious metal content of such items.
