are "toilet paper"

They certify tons of sporting memorabilia they would never have a clue about. They operate like a slabbing company. Send them the item and an outrageous fee and they will send you a COA.

Someone here got a COA for a Tiger Woods signed photo. I was there when the copy was made
As some of you know I do some charity work here which involves major sporting celebrities etc. Autographed items are often auctioned for the charities. A memorabilia company in South London looks after the donated goods, framing etc. They get goods on consignment to auction also. Its rarely genuine and he has to send most back. He sent the Woods picture to test Global out.

From time to time Global hold their own on-line auctions. They recently offered an autographed cap, reputed to have been worn by retired Australian cricketer Steve Waugh. Someone alerted Steve and a cease and desist order was served on them. He has only ever parted with one genuine worn hat (they are 'awarded' one for each test match played) and that resides in the Lords cricket museum.

I believe Muhammed Ali has already stated in the past that he never once signed anything in both names after a suspect pair of boxing gloves were auctioned in Sotheby's about 10 years ago. They initially sold for about $10k.
