The Rare Coin Values Index follows the percent
change movements of 87 carefully selected United
States coins. The purpose of the Index is to assess the overall
direction of the U.S.
rare coin market over a period beginning in January 2000 to the current
Rare Coin Values Index: Since Year 2000
The chart above graphs the combined percent change in retail
for 87 rare United States coins since
January 2000, starting at an index baseline of 100. The coin market was
strong throughout that entire decade, reaching its peak in March and
April 2009 at an index rating of 370.51. The Index stumbled a bit in
2009-10, but battled back in 2011-12 and again in 2014 to barely
eclipse previous highs. The year 2015 was a slight downer, while 2016
was an UP year, finally breaking into record territory
in September. As we move into 2017, the January reading dipped to
395.60, and down again (just barely) in February to 395.45. See

movements over the last 12 months.

The next Rare Coin Values Index chart focuses on
last 12 months. It is generated from the same body of data as the
chart above, except it's "blown up" to give the reader a closer view of
the most recent coin market activity.
Rare Coin Values Index: Over Last 12 Months
chart is a close up of the most recent 12 months of Rare Coin Values
Index activity. After coming tantalizingly close several times, the
Index finally broke into record territory in September 2016 when it hit
an all time high of 394.37, and continued to climb from there, reaching
396.98 in December 2016. . The year 2017 has started off with a
whimper, as the index fell 1.38 points in January and another 0.15
points in February to settle at 395.45. This is the first back-to-back
negative months since December 2015-January 2016.

change in retail prices for 87 rare United States
coins and is updated monthly.

How is the Index calculated?
Once a month, for each coin in the Index, the
current retail value is
estimated and compared to the previous month's estimated value, and a
percent difference is computed (it could be positve, negative, or no
change). The percent difference for all 87 coins are added together and
divided by 87 to come up with an average percent difference of the
entire group. Thus, each
coin in the Index carries equal weight. Let's call this result the
Current Month Index, or CMI.
The previous month's Index score is multiplied by the CMI to arrive at
an updated Index score.
How should I interpret the Index score?
You should interpret the Index score as a
percent change in value collectively of the 87 coins
that comprise the
which were chosen to represent the rare U.S. coin market as a whole.
The Index begins in January 2000 at a baseline score of 100. Since, for
example, the Index reached 200 in September 2004, you could say overall
prices of rare U.S. coins doubled over that 4.75 year period. In
February 2017, the Index stands at 395.45, indicating the rare coin
about 3.96 times higher than it was in January 2000. From 2009 to 2015,
the Index moved sideways and up a little, a far cry
from what we saw
from 2003 to 2009, but still positive. The Index reading was fairly
mediocre in 2014 and 2015, but performed decidedly higher in 2016,
ending the year at an all time high.
Where does the value data come from?
We obtain coin values to input into the Index
computation from a variety of widely respected coin price guides.
How were the 87 coins in the Index chosen?
Our objective was to choose a cross section of
coins whose value fluctuations represented that of the overall market
for rare United States coins. We focused on key dates the serious
collector of average to above average means commonly aspires to own.
The vast majority of coins tracked in the Index are in circulated
grades, typical of
the examples residing within the holdings of the rank and file
collector. There are no ultra rarieties in the Index.
