Why A Certificate Of Authenticity Adds Real Value To Your Fine Art Prints – David Saffir says:
In a way, the Certificate is a promise of quality and value. If the edition is limited, the buyer will know where they stand if they buy the print. If the buyer elects to sell the print down the road, the Certificate helps the print hold its value (hopefully it is increasing).
A buyer will also know that the print is made from the best materials available, that it was made by an expert printmaker, and that it is designed to last. A print like this becomes a valuable addition to a collector’s gallery, or an important heirloom.
