Product Overview
Coins with major errors are seldom encountered in United States, and this set spectacularly combines the unusual and scarce with a huge visual "wow" factor. The rare coins which occasionally escape the comprehensive screening by the US mints are highly prized and widely collected. Not only are these coins visually unusual and interesting, they also provide insight into how the coins are normally produced. This collection includes 16 different rare and interesting major United States error coins, together with a 232-page hardcover full-colour book: The World's Greatest Error Coins.
The coins are presented in four separate cases showcasing four different denominations of coins with each of four different types of major errors: blank planchets, coins struck on clipped planchets, off-centre strikes and broadstrikes. Most of the coins are in superb uncirculated condition, and all come presented in high-quality coin holders.
Case #1: Type II Blank Planchets
Blank planchets are the metal discs that would normally be struck into coins. After being punched out from a long metal strip, the discs are then fed into a machine which rolls the outer edge to produce a slightly raised edge. These are referred to as Type II planchets, ready to be struck into coins. Occasionally, a blank planchet misses getting struck and still gets into a bag of coins ready for distribution.

Case #2: Clipped Planchet Errors
Clipped planchets originate in the blanking process, when the metal discs are punched out from metal sheets. Occasionally a misfeed can occur where the strip of metal is not fed through the blanking machine far enough. When this happens, the punches strike an area of the strip which overlaps the hole left by the previous strike. The result is a blank with a piece missing. Most clipped planchet errors result in a coin with a curved piece missing.
• Lincoln cent
• Jefferson nickel
• Roosevelt dime
• Washington quarter
Case #3: Off-Centre Errors
As coins are being struck, the blank planchets are automatically fed into the coin press, where they should be perfectly centred between the dies. If a planchet lies partially outside the dies during the striking, it will receive an off-centre strike, leaving a part of the planchet blank with the design extending off the edge of the coin. Each coin struck off-centre is unique.
• Lincoln cent
• Jefferson nickel
• Roosevelt dime
• Washington quarter
Case #4: Broadstrike Errors
Broadstrike errors are produced when the collar die malfunctions. The collar die normally applies the smooth or reeded edge to the coin and prevents the metal from flowing outside the confines of the die. When a coin is struck without the collar properly in place the resulting error coin will have a relatively normal appearance at the centre, but will have a diameter that is larger than a regular coin and the design will become distorted as it nears the periphery.
• Lincoln cent
• Jefferson nickel
• Roosevelt dime
• Washington quarter
