These are quality ratings. For pins, please see the below description - for other products, please see their product descriptions for more details.
- A grade: No pin is perfect but these are the best quality in the batch! May have 1-2 minor flaws only noticeable on close inspection (examples of minor flaws include a small scratch, very small spot of under/over-filled enamel, pieces of dust under epoxy)
- B grade: Slightly more visible flaws than A grade; may have a couple more flaws (i.e. more scratches, more noticeable under/over-filled enamel, etc.)
- C grade: Noticeable scratches or defects
*Note: The back of the pin is not considered in the grading; the back may have discoloration on the metal (even A grades!).
