Write to us.

We respond to written inquiries within one business day. We do not share contact information.

A few answers we give often.

The certificate number returns no match.

A number that does not appear in our registry has not been issued by this office. Please do not complete any purchase until you have confirmed with us.

The photographs don't quite match my item.

A certificate cannot be transferred from one item to another. If photographs do not match, the certificate does not apply. Call us.

How long does authentication take?

Two to four weeks for standard trade submissions. Expedited and priority options are listed on the services page.

Can I submit my own item directly?

No. Touchstone works only with the trade. Ask the dealer you intend to buy or sell through to submit it on your behalf.
