The Grading Approach to Pins/Coins
The grading of pins or coins often comes down to the strength or weakness of the eye-appeal since the material in question is far less susceptible to wear than cardboard or paper. The areas/defects that PSA graders focus on include but are not limited to: scratches, dents, severity of rust (if present), centering of the picture (obverse and reverse), compression of the pin/coin, the overall condition of the paper (if present) on the reverse and overall print quality. Since collectible coins/pins often differ in their make-up, sometimes greatly, it is very difficult to apply one uniform grading standard to all collectibles that fall into this category. The factors above represent the basic, key elements in the PSA grading approach. At this time, pins and coins will not receive half-point grades.
