I'm new to this site, so hope I'm using it correctly. Seems every time I find a reputable company or authentication service, I find information that denounces it. This even includes PSA/DNA which I assumed to be the gold standard of authentication services. Roger Epperson, seems legit, then I find a lawsuit with email thread in which he gets nasty and doesn't honor his own guarantee. Then there's Antiquities in Las Vegas, which seems a high end reputable store in business for many years that has a negative review claiming a forged purchase. Also found negative comments about well-established trusted companies/individuals such as GAI, JSA, Drew Max (an apparent highly-trained forensic analyst), and PAAS. I realize examiners offer opinions and not 100% correct, but conflicting reports make it tough to feel comfortable purchasing autographed memorabilia. For sports items, it seems Steiner is trustworthy as their COAs are witnessed signings. The only alternative is getting something signed in front of you- not typically an easy thing to do (Eric Clapton's not hanging around my neighborhood). Advice for someone wanting to purchase autographed music items without concerns of buyer’s remorse? Thanks.
