A jeweler friend of mine has referred a customer to me to possibly buy several St. Gaudens $20’s.
What is the best authentication method? Weight/Mass?
What should authentic coins weigh ?

    FWIW, many counterfeit gold coins are of the correct weight, diameter and gold content.

    Thanks for the advice folks.
    She ended up selling them already so I don’t have to worry about it (this time).
    I’m almost relieved.

    They appear to be real. The 1909/8 and 1913-S are better dates. Suggest have the owner get them slabbed by NGC or PCGS.

    Worry is the interest you pay on a debt you may not owe.

    Perry Hall is correct, they look nice too although low res tends to look like mint frost sometimes

    Raw gold is risky these days.... In addition to the above parameters, if such a deal comes around again, have them checked on a Sigma machine. Of course, as noted above, some counterfeits are gold, though probably not full purity. Cheers, RickO
