A coin “flip” may state a coin is one thing when it is actually
another, particularly when what sets the coin apart is a feature on
the reverse. Coin dealers or their helpers make clerical mistakes on
occasion, such as writing only “1909 Mint State 64 Red,” when the
reverse of the Lincoln cent bears the V.D.B. initials of designer
Victor D. Brenner.
When discovering such an error, it has always been good etiquette
to inform the dealer, who may give you a discount when you do.
With the rise of online auctioneering, adhering to that ethic can
prove more difficult. Sometimes auction houses only post photos
showing the obverse of the coin or the images are of poor quality.
In such cases, the motto “Flip that flip” means requesting via
email that an auctioneer also include an image of the reverse, or a
clearer photo, because that side of the coin may identify it as a
rarer or scarcer variety. Sometimes a seller will post clear photos of
the obverse and reverse without realizing that the coin is a rarity.
Once informed of a coin’s rarity, if the auctioneer doesn’t answer
my email or change the designation online, it’s “game on.” I’ll bid
high and often win the lot.
You can find “reverse rarities” on several denominations. One of
the most famous and coveted is the bison with missing leg on the
1937-D Indian Head 5-cent coin — fat chance of finding that beauty.
But a less-mentioned rarity is the 3½ Legged Bison variety on the
1936-D 5-cent coin, with a difference in price of 75 cents for the
regular strike and $1,000 for the variety in Good 4 condition.
One of my most common “finds” is the “Tailbar” on the reverse of
the 1890-CC Morgan dollar, otherwise known as “VAM-4 Far Date, Tailbar
Die Gouge, Top 100” in the Comprehensive Catalog and Encyclopedia of
Morgan and Peace Dollars, written by Leroy Van Allen and A. George
Mallis (hence, the acronym VAM). An About Uncirculated common 1890-CC
Morgan dollar costs about $350 whereas the Tailbar variety nets $1,200.
Another common find is the “Micro S VAM-2 Top 100” on the 1903-S
Morgan dollar. The regular 1903-S Morgan dollar is rare generally,
with a 1,241,000 mintage. The Micro S variety is even rarer and
pricier. A regular strike in Very Fine 30 is worth about $250; a Micro
S — $600.
Another Top 100 VAM coin, the 1882-O/S Morgan dollar, features an
over Mint mark. Thousands of these coins were struck with three
reverse dies originally created for the San Francisco Mint but then
used instead at the New Orleans Mint. Several different 1882-O/S
dollar VAMs exist, with some over Mint marks stronger than others. All
are worth more than the common 1882-O dollar, which had a mintage near
An 1882-O Morgan dollar in MS-63 is worth about $75; an 1882-O/S
dollar with strong over Mint mark in MS-63, $1,600.
I have found all three rarities (Tailbar, Micro S, and O/S) by
“flipping the flip.”
I have yet to find the spectacular 1901 Morgan, Doubled Die
Reverse dollar, the “Shifted Eagle VAM-3” variety.
That gem just may merit a future column dedicated solely to it, so
that you, too, can join the search party.
