Double Denomination & Off Metal Mint Error Sales

Here are records of recent sales of double denomination & off-metal mint errors on eBay from July 1, 2009 to September 30, 2009.

1. All lots had buyers. If the coins actually changed hands is unknown.
2. A picture accompanied each lot or it was not recognized.
3. Blurry pictures or other problems are notated under “observation.”
4. Items mislabeled commanded a small premium.
5. Some lots changed hands more than once.
6. Any scratches, dents or defects notated were either in the description or grading service’s holders.
7. Auction houses that listed these errors were ignored.
8. Shipping charges are not included.

One of the most popular error types are double denominations. All have eye appeal. The higher end common dates graded over MS66 have dropped some in price. However, the sellers are still not willing to lower their ask prices. The collector must realized that some dates and mintmarks there are less than a handful known. Eye appeal will generate a higher price paid than a grade. When a new seller lists this error type and does not utilize quality pictures or descriptions, they sell for a fraction of their real value. My charts reflect this decrease. This does not mean prices dropped. It means the buyer is able to turn a quick profit if desired by offering the same piece at shows. Keep in mind that eBay sales are a small fraction of the true market. Dates, mintmarks, grading services all make a difference in value. Read over my notes to help you decipher the real market.

There are date collectors for off metals. Completing this may not be possible. For the collector that has been looking for specific dates to come on the market may have been waiting for decades. So, it is not unusual to see a MS64 example sell for the same price as an AU55. If you do not stretch for this coin, it may not show up on the market for another ten years.

Off metals have a very high eye appeal. Cents struck on dime planchets have always piqued collectors interests. Same with nickels or quarters struck on cent planchets. Check out the price variance when brown examples sell. Then compare the price to a red color sold in a lessor grade.

Multiple errors on off metals are highly desirable. There may only be one example of an off metal struck off center. Or, double struck plus off metal.

Common are the 25c 1970-D on 10c stock planchet. Try and find examples for other years or on other denominations. These are very under rated and under valued error types. Some collectors hope to determine that these errors are actually struck on a foreign blank.
