Types of Fake Coins

Kenneth Goldman has over 50 years of experience in collecting rare coins. As president of Kenneth Goldman Inc, he is a 35-year member of the Professional Numismatics Guild and a lifetime member of the American Numismatic Association.

In terms of rare coins, there are oftentimes more counterfeits than legitimate pieces. Here are a few commonly found types of fakes according to the Professional Coin Grading Service:

Cast Counterfeits: Identified by a visible seam found on the edge of the coin, these basic copies are often underweight and use base metals in place of precious metals.

Electrotypes: Electrotypes are made by impressing a real coin in a soft substance to create a positive shell.

Transfer Dies: The most commonly used technique for counterfeiters, transfer dies are created by impressing a coin into a steel die. These can then be copied using a base metal such as steel.

For nearly five decades, Mr. Goldman has attended over 95% of every major coin convention and coin auction held in the USA—something that very few, if any, professional rare coin dealers can claim. All of the major coin auction companies in business today acknowledge that Mr. Goldman is one of, if now THE, longest continuous client that they have.

With Mr. Goldman’s vast experience, he is well aware of what is rare, what has great potential, how things should be sold, and can relate his experiences with rare coins at a time when most of today’s coin dealers were still in grammar school !!,

The History of Spanish Dollars in the Americas

Since 1971, Kenneth Goldman of Needham, MA, has served collectors around the world as an expert on rare coins, advancing the field of numismatics as a significant contributor to A Guidebook for United States Coins (the “Red Book”). As a highly experienced dealer and collector, Mr. Goldman offers expertise on pieces of eight used in the Americas.

A piece of eight (a “Spanish dollar”) was arguably the first global currency, minted in Spain’s imperial American colonies from roughly 1497 until the mid-1800s. Typically a round or ovoid piece of solid or almost solid silver, the piece of eight was efficiently designed for commerce and export to the European continent in the age of mercantilism. Worth eight Spanish reales, the royal currency of Spain at the time, a silver Spanish dollar coin was assayed and minted so that it could be physically cut or broken into eight slivers (“bits”) for payments, exchange, and making change. For centuries, the Spanish dollar was the only international currency accepted in certain countries such as China and the Philippines, and it was the most common currency for interstate and regional commerce in the United States until 1857, when the Coinage Act outlawed the use of foreign coins.

Mr. Goldman is available for consultation as well as expert appraisal for all types of United States and World coins. Having been an expert witness for the Federal Trade Commission as well as for the New York State Attorney General’s Office, he is well qualified in all fields.

Rare Coin Convention Displays Costly Treasures

Coin shows and conventions are held both monthly and annually all across the United States. Not only do these venues showcase the historical significance of our money’s changing appearance, but they also provide opportunities for collectors of rare coins to search for specific, valuable items.

In New Orleans, the latest National Money Show presented rare coins and paper money worth millions of dollars. Included among the valuable objects were two 1913 Liberty Head nickels, one of which sold at auction for $3.17 million. Additionally, the show displayed an 1804 silver dollar, which was also worth over $3 million.

Kenneth Goldman, an appraiser of rare coins with 50 years of experience in the field, previously owned an 1804 silver dollar, a coin dubbed by experienced collectors as the “king” of collecting. Kenneth Goldman began collecting coins at age six and tabled at his first coin show by age 13.
