Anyone know of an approved authentication service (approved by Ebay)

[lyndilane]

Looking to have a few things authenticated and wondering if anyone is aware of a list Ebay might have approved as authorized authentication services they recognize?

There are approved services for coins and for sportscards, but not 'eBay approved' ones for stamps, although certificates from the Vincent Graves Greene Foundation, American Philatelic Society, Royal Philatelic Society, etc etc are accepted at the highest levels in the hobby.

What do you need authenticated?

By the way.

If someone tells you they can authenticate an item without having seen it in real life, they are lying.

How would they know you even own something, if all they see is pictures of it?
