Certificate of Authenticity Template
A certificate of authenticity (COA) travels with an artwork or collectible and records what it is: title, artist, date, medium, dimensions, edition number and a signature. Buyers and galleries expect one for original art and limited-edition prints. Keep a copy of every COA you issue.

Questions people ask
What should a certificate of authenticity include?
Title of the work, artist or maker, year, medium and materials, dimensions, edition number (if any), a short description, and an original signature. Some artists add a photo of the work and a unique serial number.
Can I number a limited edition automatically?
Yes. Make a spreadsheet with an edition column (1/50, 2/50…) and use the bulk generator to produce one COA per print.
Should I sign it by hand?
Yes, ideally sign each printed COA in ink, even if you also upload a signature image.
