Identifying Rim Bumps

rim

Rim bumps, or damage to the edge of a coin, is typically overlooked by the eager bidder or busy auctioneer. But they also are among the biggest disappointments in collecting because they greatly devalue the condition of a coin.


Buyers should always inspect the rim before bidding on a lot. Sometimes the rim is bent, as in the photo above.

Sometimes the edge is damaged, as in the photo below.

Sometimes the damage is barely noticeable on most of the surface of the coin, as in this photo:

You’ll notice that in each of these examples the auctioneer identified the rim bump on the flip or in the description. That is important. By acknowledging flaws such as this, you will be building confidence in your bidders.

Finally, always scan the condition of a coin not by looking straight at it (you can be taken in by luster, devices, etc.) but by beginning at the noon position of the rim and slowly inspecting the coin around the entire edge before making your way little by little toward the center of the lot.
