The coins PMD list

Another coins List: Some Common Examples of PMD



type and description


Also called counterpunch, punchmark, or (inaccurately) counterstamp, this is a mark punched into the coin, by private individuals or organizations, for a variety of reasons.

Shown here is a penny marked with an effigy of JFK.  Other common marks include outlines of US states, Masonic symbols, letters, etc.  Here is a gallery of countermarked pennies.  Such coins usually have no added value, other than as novelties.

Exceptions (very rare):

  • Coinage used in early trade in China chopmarked to verify silver content (examples, info); and

  • Foreign coinage counterstamped (validated for use) by local or national governments (example).

Dryer coin, or spooned coin

Coins trapped inside clothes dryers may exhibit two different types of damage from the combination of heat and repeated impact.  Some dryer coins have smoothed, rounded-over wear, from damage to the surfaces (upper left).  Others have raised and/or rolled rims from repeated impacts to the edge (upper right).

More smoothed/rounded dryer coins.

More rolled edge dryer coins.

Spooned coins also have raised rims from having been struck repeatedly along the edge, usually with a spoon, for example to make a ring.  These are generally rougher-looking than dryer coins with similar edge damage (lower image).

Coins damaged in these ways have no additional value.

Coin roller damage

Some coin rolling machines scratch the end coins of the roll, as the wrapper is applied and crimped.  This results in a circular or semi-circular scratch near the edge.  This damage confers no value to the coin.

Painted/plated coin

A coin that has had another layer of material added to it.

Plating copper pennies with zinc or another white metal, like the one on the left, is a common school science experiment.  (Exception: 1943 US pennies were produced from zinc-coated steel, rather than copper alloy.)

Other examples:

Some coins (e.g. quarters) are painted by businesses to mark them as “house money” (example).

Some companies colorize new coins to sell as collector items (example).

All of these practices are considered damage to the coin.

Holed coin

A coin that has had a hole punched through it, for example to wear as a charm or bracelet, or kept on a string, practices that were more common in bygone days.  More examples.

To be distinguished from coins with holes as a feature of the design, such as these.

Like other forms of damage, a hole through a coin decreases its collector value.
