Error Guide

Part One

An error occurs when there is a problem with the take of the coin, not in the die itself. There are three different types of errors, planchet errors, die errors, and mint strickle errors. Some examples are : mint duplicate, laminations, struck through, off center, clipped planchets, capped dies, dirt filled dies, die alteration strikes, and die clashes .
Varieties are mistakes in the die and many coins get minted that are precisely the lapp. There are literally hundreds of Lincoln cent varieties. Some examples of different types of varieties are : double dies and re-punched batch marks .
many collectors nowadays do n’t understand the difference between the two and will advertise a double over die as an error mint and so on .

Mechanical Doubling

mechanical or car doubling ( MD ) occurs when there is a trouble in the strike work, not with the die itself. These errors do not appeal to collectors the means doubled dies do and do n’t have much collector value at all.

The machine doubling produces a flat, ledge like junior-grade persona that is easily distinguished from the rounded, raised doubling produced by a double die. MD besides narrows the devices where a double die will make them appear wide-eyed .
Cents before 1990 had the mint mark punched in by hand after the die was made, so a true double die before 1990 would n’t show the like double on the mint mark. It is possible that a true double die will besides show signs of MD .
The case below shows a 1969-S with classical MD. Notice how the devices appear smeared or pushed to one english. The raise parts are besides narrower than the original digits would be. You can besides see how the secondary persona is flat compared to the round chief effigy .

The exemplar below shows a grease filled die error. This is a 1994-D with the 994 & D parts of the design by and large missing. This is caused by grease build up on the die clogging the 994 and the “ D ” .

In 1922 there were no cents minted at the Philadelphia mint because of problems at the mint, so all of the cents for that year were minted at the Denver mint. Three different dies produced some cents that either did not show a “ D ” batch mark at all or showed a very weak one. The two dies that produced the unaccented but visible mint marks were ascribable to satiate dies. The “ D ” on the die became filled with dirt or grease. The remaining die had the mint mark grind off of the hub by abrasives and was never on the die then there is no tracing of it on the coins produced by that die. Either of these types are valued by collectors. A 1922 no “ D ” Lincoln penny in uncirculated circumstance can fetch upwards of $ 20,000.00. even in good condition they are worth several hundred dollars. Be aware that this is one of the normally counterfeited Lincoln cents. Cent production was direction down that year, then even a 1922-D in uncirculated condition can be worth over $ 200.00 .

Capped Die Errors

A die hood mistake happens when a mint sticks to the fail and strikes more coins. As it continues to strike more coins, the cent that is stuck to the die becomes shaped like a bottle ceiling, hence the name “ Capped Die ”. Some collectors will refer to these as Bottle Caps or Mushrooms .
