Coin Chemistry Preservation and Cleaning Weimar W. White

Description

This book presents the author’s ideas on cleaning and preserving coins in your collection. This book is a compilation of articles on coin chemistry written during the last 19 years. Some deal with the cleaning of coins to remove oxidation products and/or foreign matter and some deal with good coin care in terms of preventing chemical wear from oxygen and sulfur. He focuses on silver coins, since they are most susceptible to tarnishing, and gives examples of coins that should and shouldn’t be cleaned. He names substances that should be used, and provides information about the albums that best protect against toning. Many silver coins, in the wrong albums, will continue to tarnish. Slabbed coins also can continue to tarnish, he says, if not protected.

He also talks about restoration of damaged coins, for example an 1876 CC half dollar that has been holed, probably for jewelry. Since the coin is at least a desirable grade AU-58, he had it restored by an expert, using material from silver coinage. The patch is so good it can only be detected with a high-powered microscope. White provides the contact information for the restorer, and for album purchases.

This book is a Third Edition, dated 2012, and would be a valuable addition for those who specialize in cleaning and preserving coins, and for novices who would like to know more about the subject.
