In the April Monthly issue of Coin World, I introduced a multi-part
series on well-known coin dealers who have been in the hobby
professionally for 40 or more years. Featured in the first part were
Q. David Bowers, Larry & Ira Goldberg, Fred Weinberg, Jeff
Garrett, Steve Ivy and Julian Leidman.
In this installment, which first appeared in the April 13, 2015,
print edition, I look at the career paths taken by John Dannreuther
and Tom Caldwell.
Tennessee dealer John Dannreuther was one of the six professional
numismatists that formed the “dream team” that authenticated the
George Walton example of 1913 Liberty Head 5-cent coin in 2003. He
became a full-time dealer in the early 1970s.
“My father, Victor John Dannreuther, introduced me to coins around
1955, although I had collected stamps first,” Dannreuther said. “I was
seven years old. Although I was fascinated by stamps, coins soon
became my main interest. In 1956, my grandfather gave me the 1837
Reeded Edge half dollar (the only coin I still have from my early
collecting days) that he had carried with him during World War I. For
my tenth birthday in 1958, my parents gave me a five dollar gold coin.”
Dannreuther said he became a full-time dealer by family
circumstances. His father was suffering from a deteriorating eye
disease and asked John if he would start selling his coin collection,
an effort that began in earnest in 1973. John, known simply as JD, was
now a coin dealer.
“Today, breaking into the business as a dealer is very easy, as
coins are now graded, guaranteed genuine, and encapsulated,”
Dannreuther said. “Working for a major dealer is how most of the new
coin dealers become successful. I was very lucky and became associated
with some of the most successful dealers (Jim Halperin, David Hall,
etc.) and they helped guide my career.”
Dannreuther considers the most interesting story of his career to be
formation of Professional Coin Grading Service in the mid-1980s.
“David Hall, Gordon Wrubel, Bruce Amspacher, and I met for nearly
two years at coin shows and discussed forming the grading service,
although at first it was just a book project!” Dannreuther said. “I
would say that the most important day in my career was the meeting
[when] David Hall brought the first ‘slab’ .... That meeting was the
real beginning of coin encapsulation. At that meeting, we all felt
something really special. It is difficult to put into words, but we
all left that meeting realizing that the coin business was going to be
Dannreuther said he also enjoyed writing PCGS’s Official Guide to
Coin Grading and Counterfeit Detection.
“Trying to write the standards that PCGS was employing to grade the
coins was quite a challenge,” Dannreuther said. “I had to think about
the reasons a particular grade was assigned to a coin. This made me
realize how hard it is to describe the grading process.”
Dannreuther is also the co-author with Harry W. Bass Jr. of U.S.
Gold Varieties, A Study of Die States, 1795–1834.
A chance late 1960s encounter with an 1867 Shield, With Rays 5-cent
coin that a teenaged Tom Caldwell received in school lunch money from
his mother triggered a lifelong hobby interest and numismatic career.
Investigating, and learning that the 1867 Shield, With Rays 5-cent
coin was worth $20 pushed Caldwell to delve further into numismatics.
Caldwell is president and owner of Northeast Numismatics in Concord,
Mass., and is celebrating 50 years as a professional numismatist.
Caldwell said during the 1960s and 1970s, he took advantage of the
numismatic knowledge available to him by attending meetings of the
many local coin clubs that were then prevalent in the area around
Littleton, Mass., including his high school coin club.
Caldwell established a coin shop in the basement of his parents’
home and took tables at local coin shows and flea markets.
“My early mentors were my parents, who, while having no knowledge of
coins, were always there to encourage me, driving me around for years
to virtually any location where I could indulge my numismatic passion
and curiosity,” Caldwell said. “At around the same time, a regional
show was established by Ed Aleo, and the Bay State Coin Show continues
to thrive. Ed has been a longtime friend and early mentor, and we at
Northeast Numismatics are proud to help sponsor this popular
semiannual show to this day.”
Caldwell said he learned early in his professional dealings to treat
potential customers equally, whether a young or novice collector just
starting out or a seasoned hobbyist seeking to spend five or six
figures on a coin purchase.
What drove the coin market 30 to 40 years ago was the building of
coin sets without considering the investment component, Caldwell said.
Telemarketers and Wall Street investors took the hobby into
different directions, transitioning the hobby from a pastime to a
full-blown industry, Caldwell said.
The market has been significantly influenced by the plethora of
numismatic products engineered and marketed by the nation’s largest
coin dealer — the United States Mint, according to Caldwell.
“Up until 1982, a $10 bill would buy you every product the Mint
produced, that being a Mint set and a Proof set,” Caldwell said.
“Today you can spend $5,000 and not purchase half of the Mint offerings.
“As collectors embraced the Mint products, this diverted dollars
from traditional early coinage. Eventually the grading services
followed suit, which started gaining popularity in the mid 1980’s.
“At one point early in the certification era, some thought that all
the available worthwhile coins would be graded, and the eventual
degradation of the grading services would occur. Bulk grading,
re-grading, the prominence of the internet, and the excessive Mint
offerings have indeed changed any of those notions.”
Caldwell notes that most of the millions of coins graded annually by
the major grading services are modern issues.
The introduction by Professional Coin Grading Service and Numismatic
Guaranty Corp. of registry sets of certified coins has been popular
with collectors and investors, continuing to “influence the market and
prices for high end material.”
Caldwell notes along with other longtime hobbyists that the Internet
and World Wide Web have had a major impact on numismatics.
“It’s difficult to imagine the industry nowadays without the
prominent use of all the advantages the internet has to offer,”
Caldwell said. “Needless to say, the web has become involved with
nearly all of us on a daily basis in countless aspects of our lives
both personally and professionally. Those of us in the rare coin
business that have embraced advancing technology have been major
beneficiaries, and have helped to move the industry further into prominence.
“At Northeast Numismatics we have had a web site
(www.northeastcoin.com) since before the turn of the century, and this
has become a necessary tool to stay competitive and reach buyers and
sellers on an everyday basis. Long gone are the days of primary
dependence on print ads in trade publications to reach customers.”
While coin shops were the place for collectors to build their
collections, Caldwell believes that now only a small percentage of
numismatic transactions take place in a storefront.
The cause: the Internet, Web and third-party grading. Increased
technology allows for the online presentation of quality images that
collectors can view in the confines of their home or office.
“This has played a significant role in internet buying, resulting in
a dramatically increased confidence between buyers and sellers alike,”
While local, state, regional and national coin shows still are
important arenas where dealers, collectors, and investors can conduct
business, public participation at shows has dropped off, he said.
“More buyers are going to dealer web sites as well as eBay and other
auction venues,” Caldwell said. “Shows do, however, continue to serve
as an essential outlet for dealers. It is probably fair to say that
the majority of transactions are dealer to dealer at shows across the
