Early IHCs were often called "nickels" or "nicks" due to their copper-nickel composition. Source: http://lynncoins.com/indian-cent-rolls.htm (Note: I do not know what they called 5-cent pieces... "5-cent pieces"? "half-dimes"?)
The 1873 open 3 & 1873 closed 3 varieties were popularized to collectors in the 1960's by a gentleman named Harry X Boosel . He was known as "Mr. 1873"
The 1864 L, even dealers miss the L on some of them. Like I mentioned, I've cherried 13 of them That is a date, not a variety
Speaking of the 1909 . There are NO varieties to the 1909-S IHC. All do show a slight doubling on the upper loop of the last 9. This was due to very slight doubling on the hub that produced the 2 obverse dies. This was (1909) the 1st year the date was incorporated into the master die. Meaning there can be no date positional varieties.
The 1871 'Shallow N' variety can be tough to spot. I equate it to trying to distinguish WAM/CAM of today. With practice and study they can be readily discerned, but at first, a side-by-side is a must.
Yeah, I read the question too fast. I found more 1909 IHCs. The 1864-L makes sense in terms of the question, cherry-picking. The pointed bust and denticle it points to are the give-aways. I have one. It's in G.
Oh no, I couldn't do it! I'm not an expert cherry-picker like you! Tell us the truth. Did you cut down the cherry tree? You did, didn't you? Don't feel bad, George Washington did, too. But at least he was big enough to admit it, unlike you.
Not an expert, just a reader. I read everything to pick up ideas of varieties. The Guide Book/Red Book is a great start. The there is a reference book on nearly every series of coins out there.
The composition and thickness of the Indian Head Cent were changed in 1864 to mimic the widely accepted Civil War tokens that were circulating during that period.
