I bought a Datsyuk 2 years ago, the one with the 'wind' holes in it, $225. They put a holigram on it and a matching one on the COA. The seller seems to be legit and sells alot of merch on there, I was just thinking for that price, it should have a COA. A couple flags went up, I have several stick cards with that yellow one on it.
I did buy a broken Homer shaft with no COA for $20 at the Joe. I was more happy with that than the Datsyuk lol. I think my plan was to check the Joe and see if they have any available, but the tend to keep some in the rink store too.
