James Spence Authentication, LLC (JSA) offers several different forms of authenticity which includes a service specifically designed for approved auction houses. These Auction House Letters of Authenticity (LOA)
are exclusively created to accommodate national auction houses keeping in mind the large volume of signature material presented in a specific catalogue. The winning bidders receive our Auction House LOA on our proprietary watermarked paper containing the lot number, item(s) description (per the auction house) and date of the offering.
These generic LOAs differ from our premium documents in as much as they are preliminary reviews of the items and do not go through the rigors our full examination process. Unlike the premium JSA LOA, the Auction House versions do not contain the live notarized signature of James Spence, a high resolution digital scan of the signature(s), certification number and sequential sticker, nor our own specific description of the offered lot. The text provided by the auction house is solely their verbiage.
If the winning auction bidder elects to have the LOA upgraded to our premium service, JSA charges a $50 upgrade fee per individual item. This service is recommended by JSA and will ensure the highest level of our opined expertise. In the rare event that our opinion differs from our original consultation with the auction house, no upgrade fee will be charged. Only original auction house JSA LOAs
are accepted for our upgraded service. Photocopies are not accepted. It is important to for all of our customers to fully understand the differences in our products to avoid any misconceptions or confusion. NOTE: Policies are subject to change at the discretion of James Spence Authentication, LLC
