I have bought 3 jewelers loupes and a black light flash light for starters to examine cards from here on out (they have not come in yet) This reminds me, I had read that counterfiets [can/do?] react different under UV light, hence buying the black light, I do have a black light I was able to shine on charizard last night, and it looks EXACTLY the same color as any other holo I compared it to, front and back
