Double Denomination & Off Metal Mint Error Sales

Here are records of recent sales of double denomination & off-metal mint errors on eBay from April 1, 2009 to June 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 slightly dropped in price. However, sellers are still not willing to lower their ask prices. The collector must realize that with some dates and mintmark examples there are less than a handful known.

When a new seller lists this mint error type and does not utilize quality pictures or descriptions, they sell for a fraction of their real value. My charts reflect this decrease in price. This does not mean that prices dropped. It means the buyer is able to turn a quick profit by offering the same piece at shows.

Keep in mind that eBay sales are a small fraction of the true market. Dates, mintmarks and 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. Multiple errors on off metals are highly desirable. There may only be one example of an off metal struck off center or a double struck 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 foreign planchets.
