I have a Kovy replica jersey, a Kovy knock-off jersey (the only knockoff I have. Didn't know it was one as a friend ordered it and I didn't know he was going that route), and a Kovy Accelerator jersey (I know, I collect crappy jerseys too lol).
The replica and Accelerator ones I think I will just put into storage. The knock-off I might donate as I never wore it anyways.
I also have a signed puck by him. I am keeping it in my collection.
