Artifacts that have been certified by the IAGA often see an increase in price and demand. Buyers and sellers trade with more confidence by mail, phone, or on the internet, because they know what to expect of an IAGA evaluated artifact. Buyers that know what they’re getting are more likely to be confident and aggressive. Sellers can be assured they’re getting paid a fair price for their artifact’s condition. And because the collector knows what to expect, fewer items are returned because of dissatisfaction.  Collectors trust IAGA artifact certification.
