Every pin maker grades their pins differently, and standards change from artist to artist. I do my best to inspect each and every pin and sort them into A, B, and sometimes if needed, C grades.

A grades have extremely little no flaws that are usually only noticeable at certain angles or upon extremely close inspection. Flaws include:
- minor surface scratches
- minor bubbles in the enamel
- minor misalignments in the screen printing
- minor marks in the enamel

B grades have small-medium flaws and are offered with a small discount. Flaws can include:
- scuffs or scratches
- marks in the enamel
- under or overfilled enamel
- bubbles in the enamel

C grades have very noticeable flaws listed above and are offered with a large discount.
