Selected title: Slabbed Coins
Explanation: Coins which have been submitted to one of the professional grading services for certification as to the grade of the coin. The coins are examined by the grading services experts, assigned a grade and sealed into a hard plastic 'slab' with a label indicating the coin type, date, mintmark, variety and grade. Often a certified coin is accompanied by a photograph certificate. The holder affords protection from subsequent wear or damage but is not airtight and therefore will not prevent toning. Because any tampering with the holder will be obvious, it also prevents replacing the certified coin with something else. The grades assigned to the coins are accepted as accurate by most collectors and dealers. Because of this, slabbed coins are often traded sight unseen.
