Pricing questions

What is the difference between the digital certificate and the physical + digital certificate?

The physical + digital option includes examination of the original item in my studio and a printed certificate with security features, in addition to the digital version. The digital certificate is based on photographs only: it is more affordable, but its scope is limited, because without the original it is not possible to examine pen pressure, ink or the support.

Do you charge if the signature is not authentic?

The preliminary assessment from photographs costs €25 and is deducted from the price of the certificate. The fee pays for the expert examination; it does not guarantee a certificate. If the signature does not clearly pass the examination, no certificate is issued and I explain the reasons in writing.

Do you offer discounts to dealers and auction houses?

Yes. For regular volumes I prepare a tailored professional rate.

How do I pay?

By bank transfer or PayPal. You receive the payment details when you accept the quote. The fee pays for the examination: if the signature does not pass the analysis, no certificate is issued.
