Avoid extra holes, split wraps, excessive missing parts, after market non brand mounts, PEARL TOM MOUNTS, "professionally recut edges" when the professional was a framing hack with a hand held router, and, have an idea for the genuine article to avoid being scammed by fakes.
Yes, people will fake certain vintage snares, badges, whole drums. Even in player grade kits. A faked player is often harder to spot than a pristine collector.
Player does not mean a set that has enough holes to make a brothel look like a safe haven of vestal virgins. Player means the set will have gig wear, it will have been used. It will have been played. Player does not apply to a set that was found floating on the Mississippi after Katrina, or was stored for 25 years in a leaky basement or barn. It does not apply to a set some guys grandson spray painted in clown posse colors. And in my opinion, it does NOT apply to a Rogers drums set that has Pearl pipe mounts and a rack.
And the most important, know what you are looking at. Do your due diligence in research.
