Lapel Pin - Additional Markings

Additional Markings

• Back Stamp - A pin's back stamp contains information about the pin and can include copyright information and edition size.

• Artist Proof - Artist Proof pins (or AP pins) are created during a manufacturing run to verify quality. AP pins have a small AP stamped on their back. Some collectors value the AP markings, but most AP pins have minimal difference in secondary value because the markings are not normally visible.
