Why 1877 is the Undisputed King
Following the severe economic Panic of 1873, millions of base-metal small cents accumulated in commercial bank vaults. By 1877, demand for new pennies was virtually zero, resulting in a tiny regular-strike mintage of just 852,500 coins (the lowest in the entire 50-year Indian Head series). None were saved in original uncirculated bags, making 1877 the premier key date.
The 'Shallow N' Reverse Diagnostic
The ultimate secret weapon of professional numismatists: ALL genuine 1877 business-strike Indian Cents were struck with the Type 1 'Shallow N' reverse hub. On this hub, the diagonal bar of the letter 'N' in ONE is noticeably thin and weak. In 1877, the mint introduced the Type 2 'Bold N' hub for proofs, but NO genuine business strikes were made with Bold N. If you see an 1877 with a Bold N, it is 100% counterfeit!
Detecting Altered Dates & Electrotypes
- 1873 Alteration: Fraudsters shave the curl off the final '3' to make a fake '7'. Check for tool gouges, uneven patina, and improper spacing.
- 1878 Alteration: The left loop of the '8' is smoothed into a '7'. The digit will appear unnaturally thin or misshapen.
- Electrotypes: Cast copies created from genuine museum specimens exhibit a hidden seam line running around the center edge of the coin.

Frequently Asked Questions
Why is the 1877 Indian Head Cent so famous and expensive?
The 1877 is the undisputed key date to the entire Indian Head Cent series (1859–1909). With a tiny mintage of only 852,500 struck during a post-Civil War economic slump, virtually every single coin was spent into daily circulation. Because almost none were saved by contemporary collectors, finding genuine problem-free examples in any grade is exceptionally difficult.
What is the 'Shallow N' test for the 1877 Indian Cent?
All genuine regular-strike (business-strike) 1877 Indian Cents were pressed from the older Type 1 reverse hub with a 'Shallow N' in the word 'ONE'. On this hub, the diagonal crossbar of the 'N' is faintly impressed and shallow. If an 1877 cent has a thick, boldly raised diagonal bar ('Bold N'), it was struck from the post-1877 hub and is guaranteed to be an altered date or counterfeit!
What common dates are altered to fake an 1877?
The two most commonly altered coins are the 1873 and 1878 Indian cents. Unscrupulous individuals scrape off the lower loop of the '3' or file down the '8' to resemble a '7'. Under high magnification, tool marks, recessed metal depressions, or mismatched patina will immediately betray the deception.
What is the minimum grade to see 'LIBERTY' on an Indian Cent?
On an Indian Head Cent, the word 'LIBERTY' is stamped across the headband of the headdress. To see at least 3 letters of LIBERTY, the coin must grade Very Good (VG-08) or higher. In Fine (F-12), all 7 letters of LIBERTY are visible, and in Extra Fine (EF-40), all letters are sharp and crisp.
Can a heavily worn 1877 cent still be valuable?
Yes! Even in About Good (AG-03) or Good (G-04) condition where the feathers are worn smooth and LIBERTY is gone, as long as all four digits '1877' are clearly readable, certified examples sell for $750 to $900.
Did the 1877 Indian Cent come in bronze or copper-nickel?
By 1877, all Indian Cents were struck in French Bronze (95% copper, 5% tin & zinc) with a weight of 3.11 grams and a diameter of 19.0 mm. Copper-nickel planchets were only used earlier from 1859 to 1864.
Why should I never buy an uncertified raw 1877 Indian Cent?
Because the 1877 cent is one of the most frequently counterfeited and altered coins in American history, purchasing raw (unslabbed) specimens is extremely hazardous. Over 60% of raw '1877' coins submitted to major grading services turn out to be altered dates, cast fakes, or electrotypes.
