I should have posted this a long time ago for Rush fans.
There is a Facebook page for authenticating Rush signatures and more specifically Neil Peart and his drum sticks. Post your item on this FB page for verification. It's run by Michael DF Lowe and he is Neil Peart's authorized authenticator. You will get inputs from other members but it is Michael's word that is final.
Hope this post helps in the battle against forgeries. Below is the FB forum name;
