Don't even worry about said coin, but is the slab in tip top shape? Does it have scratches and hairlines? Does the label have its original luster and color? Make sure your slab is better then the next guys...
And get your slab slabbed. With all the Chinese fakes you have to take care to get an authentic, unaltered slab.
Buy the coin and not the slab will work for hand to hand combat, but not very good for internet purchases ... Its all about the slab without the hand to hand combat .. Lol ...
....mint with mint tags, that is all I am saying. Btw, they do have products to protect the slabs. Its a plastic coating that can make sure the plastic you are really collecting stays pristine. You know, as many layers between you are the actual coin as possible is the goal. Eh, I will stay in my little dark corner of the hobby, happily handling my coins and being made fun of not being a "real" collector since they are not encased in plastic.
Oh, no! You'll destroy the original extruder luster! Then your slab will only ever be able to get a "Details" grade... I mean, it'll be a Details slab... no, wait...
Anyone who would rather buy the slab instead of the coin is more than welcome to send the coins to me. Chris
Can I make an exclusive arrangement with your business to provide "Plastic Assurance Professionals" beans as a fifth-party confirmation of the coin's slab's quality? (Or are we up to sixth-party by now?)
Will you offer a conservation service for problem slabs as well? Or should we just continue to use POLY-CARE on them ourselves?
We can even cut out the middleman and skip the messy coin at the begining. We can just start from the label.
When I first got into collecting, the slab meant one thing - that a professional had guaranteed it was authentic - especially with gold coins. I've had a few fake pennies and a few fake foreign silver coins (ok, well silver colored) come through my hands. Some are obvious, some are less obvious. Getting an authentic coin with an image that matches to the coin gives me a warm fuzzy that it's authentic. I've cracked a couple out (damaged at least one doing it) just to do a bit more detailed looking and feeling. But come on, don't knock the slab... To each their own!!!
