2021 Jefferson Nickel and Roosevelt Dime Error Coin Guide

Book excerpt: Welcome to the Jefferson Nickel and Roosevelt Dime Error Coin Guide for 2021. The wide range of auction prices paid for error coins makes this guide necessary for a collector to evaluate, encapsulate, or purchase an error coin. There are three significant categories of coin errors: - Planchet errors - clipped planchets - elliptical, fragment, ragged, tapered, thin, and thick. Wrong planchet, foreign planchet - Die errors - broken dies, collars, and doubled dies, - Striking errors - Bonded, broadstruck, brockage, clashed dies, cracks, double struck, indent, flip over, and much more. After 20 years, this coin guide remains unsurpassed and the most comprehensive error coin guide available. No other guide has the number of error listings and error types as presented in this guide. Even with the US Mint using the best technology for producing billions of Jefferson nickels and Roosevelt dimes, there are still modern-day errors in circulation. The wear and tear on the dies, the dies' reworking, and malfunctions in the minting process create many mint errors escaping detection.With so many error coin listings in this book, it would be a significant challenge to add photographs for each error. Error definitions with photos in this guide show the types of errors that can occur and should represent most errors.
