EBTH, where possible, will do it's best to determine the authenticity of many items.  As we are an intermediary between seller and buyer, we use all of the tools at our disposal to accurately represent the items sold on EBTH.  Here are just a few ways that we do so:

Jewelry, Gemology, and Coins

If you are bidding on any of these items that have been evaluated by our in-house gemology team, the item will note the graduate GIA (Gemological Institute of America) gemologist as seen below:

These items will not have accompanying paperwork created by our team.  If the item already has accompanying certification, paperwork, or original boxes and tags that were provided by the seller, then those will be included with your item.  The description and photographs will disclose what is included, as well.

Certificates of Authenticity

Sports memorabilia, art, and celebrity autographs are just a few of the kinds of things you will find at EBTH.  When these items have been authenticated before being consigned with EBTH, we will include the certificate of authenticity in the sale.  We do not include a photo of the certificate in order to prevent reproduction.

For select items, EBTH partners with James Spence Authentication (JSA) to provide a visual inspection for items to verify the authenticity.  These items will not have Letters of Authenticity provided for them, unless the seller decides to do so.  These items will appear with the JSA logo on the item. 


When an item is able to be reviewed by our Fashion Expert (FASX for short), it will be noted with the FASX tag in the description.  It may also be accompanied by the initials of the expert that reviewed the item for internal purposes.  EBTH uses Entrupy as well as years of combined experience in order to test the authenticity of fashion items.
