While there are various types of dollar coin errors, some of the most notable include:
- Missing Edge Lettering (or “Godless Dollars”): These coins lack the inscription “In God We Trust,” the date, and the mint mark along their edges. This happened when a number of coins missed the edge-lettering step in the minting process. The 2007 George Washington dollar is particularly well-known for this error.
- Doubled Edge Lettering: This error occurs when a coin passes through the edge-incusing machine twice, resulting in two sets of inscriptions on the edge. Inverted doubled edge lettering also occurs when the coin goes through the machine twice but is flipped over between passes, causing the lettering to appear in opposite directions.
- 2000-P “Wounded Eagle” : This error features a die gouge on the reverse of the coin, resembling a wound on the eagle.
- 2000 Sacagawea dollar – Washington quarter mule: This rare error features the obverse of a Washington quarter and the reverse of a Sacagawea dollar struck on a gold-colored dollar coin planchet. It is one of the first known authentic mule coins to be released into circulation by the United States Mint.
- 1979-P “Wide Rim” (or “Near Date”): The date on this coin appears closer to the rim than on regular issues, according to CoinHub Media.
- 1979-P “Doubled Die Obverse” : This coin displays doubling on Liberty’s portrait and the motto, says CoinHub Media.
- Struck on Wrong Planchet: Some dollar coins have been accidentally struck on planchets (blank coin disks) intended for other denominations, leading to unusual shapes or sizes. An example is the 1979 Susan B. Anthony dollar struck on a nickel planchet.
- Off-Center Strikes: In this error, the coin design is struck off-center on the planchet.
If you believe you may have an error dollar coin, it is recommended to have it authenticated and graded by a professional coin grading service to determine its value.
What is the mistake on the $1 coin?
From my experience, The rare 1984 $1 coin was struck on a 10-cent blank in error, instead of a $1 blank, meaning the coin is silver rather than gold. One of the coins went to auction with a price guide of between $2,000 and $3,000 this week, sold by auctioneers Roxbury’s Auction House.
How to tell if a $1 coin is valuable?
Good point! U.S. dollar coins worth money are hard to identify at a glance. Their value lies in where they were minted, their historical significance, mintage, precious metal content, whether they are error coins, and their condition.
What are the errors on US coins?
There are several types of planchet errors that include: improper alloy, wrong stock, imperfect blank, and lamination. A planchet error may be caused by an improper alloy mixture. Improper alloy mixtures occur when the sheet stock contains uneven layers of the metals intended for the type of coin that is produced.
