Every year this guide is updated with new and exciting finds. No other guide presents as much information about error collecting. Photos of all errors with complete descriptions validated by PCGS and NGC terminology provide collectors with information to identify the type of error.\n\nAll types of errors from striking, planchet, and dies that collectors can locate from old collections, bank rolled coins, and circulation. Many error coins circulate without detection since most are not well known.\n\nSome errors are difficult to determine, but some great tools are available to make error detecting easier, especially for RPM errors, some of which are easy to overlook. There are eight doubled die classifications for explaining the types of doubled dies created by die creation.\n\nMajor Error Categories\nDie Errors\nDie errors are created from broken dies, cracked collars, hub errors, misaligned dies, doubled dies, and repunched mintmarks.\nAbrasions (scratches)\nBar\nBIE\nBroken hub\nBroken punch\nCollar break\nDebris in hub\nDie adjustment\nDie breaks\nDie crack\nDie cud\nDie cud retained\nDie gouges\nDie wear\nDoubled die\nFilled dies\nFilled letters and numbers\nFinned\nMintmark\nMisaligned dies\nMisplaced date\nMissing details\nMule\nPartial collar\nTilted collar\nMint Striking Errors\nMint striking errors result from the mint stamping process.\nBonded\nBroadstrike\nBrockage\nCanceled\nChain\nCollar clash\nCounter brockage\nCupped\nDouble denomination\nDouble-struck\nExtended rim\nFlip over\nIndent\nMated Pair\nMultiple Struck\nOff-center\nReverse Brockage\nRotated\nSaddle\nStrick over\nStrikethrough\nUniface\nPlanchet Errors\nThe coin blank and the blanks with upsets on edge are called planchets. A type I planchet is the coin blank itself. A type II planchet is the coin blank with the edging rolling. Planchet errors include blanks used in the minting process with cracks, clips, defective lamination, occluded gas, unplated, wrong metal, and wrong planchet.\nBlank\nClipped\nDefective\nForeign\nFragmented\nImproperly annealed\nLamination\nLamination retained\nOccluded gas\nSplit\nThin\/Thick\nTilted\nTransitional\nUnplated\nWoodgrain\nWrong metal\nWrong planchet\u003cbr\u003eASIN: B0B1C2Z52L\u003cbr\u003eVSKU: PKV.B0B1C2Z52L.G\u003cbr\u003eCondition: Good\u003cbr\u003eAuthor\/Artist:McDonald, Stan\u003cbr\u003eBinding: Paperback\u003cbr\u003e\u003cb\u003eNote:\u003c\/b\u003e Any images shown are stock photographs and product may differ from what is shown.  \u003cbr\u003e\u003cb\u003eCondition Notes\u003c\/b\u003e: A well-loved companion.
