Pin grading is an essential process to ensure the product’s quality. Every pin maker has his own grading system and his tolerance threshold, but it usually starts with a visual appreciation of the pin. I look for any potential defect, scratch, missing color area, spot, … Pins are categorized in two groups, the list below clarify the meaning of each grades. Please keep in mind that enamel pins are handmade item, they cannot be 100% perfect.

A grade pins (standard)

It’s the highest quality, some may have minor defects only visible during a thorough examination, but they still look very nice.

Some example of A grade defects:

• Slight color/glitter overflow
• Unnoticeable rubbles
• Minor imperfections

B grade pins (second)

They are close to A grade, nevertheless they have noticeable flaws. Obviously, it involves a lower price.

• Minor air bubbles, scratches, dents
• Small color overflow
• Noticeable underfilled areas (color or polish)
