Patterns, there are two of them and they are different from each other.

I defer to what the ad in the comic books told me back in the late 1960s: 1804 silver dollar.

Runners-up: 1913 Liberty head nickel, 1894-S dime

Sounds like your sentimental favourite.

What are the criteria for being King?

I consider it a coin without which you cannot collect the series. The shorter the series, the more this becomes an issue. So the 1916 Standing Liberty quarter, and the 1918/7 are keys, there are short sets or subsets that can exclude them. There are keys in the Walking Liberty series as well, but you can do 1941-1947 short set. You can do 1941-1945 short set in Mercury dimes and skip the keys.

You can't do this with the 20c pieces. The 1876-CC makes the whole series uncollectable. That, I think is the King of keys. It kills the collectability of the entire denomination.

"What are the criteria for being King?"

For me, a "set" consists of one each of "regularly issued for circulation" coins.
And once found in circulation.
(The 1894-S "Ice Cream Dime," found in circulation, doesn't count.
It was not a regularly issued coin.)
No proofs, no patterns, no non-sense!

Thus, the 1909-S VDB Cent, 1913-S Type Two Nickel, 1916-D Mercury dime, etc.
All are available for a price and needed for a complete set by my definition.

"The collection is in your mind. Dispose of your albums and free your mind from the tyranny of holes."
Amen, Amen, AMEN!

I currently have a few sets and have the key dates of:
1909S VDB for Lincoln Cents
1877 for Indian Head cents
1916 D for Mercury dimes
1885/1886 Liberty nickel
1921 Walker
1928 Peace dollar
1913 S for Bison Nickels
1858 Canadian Large cent

Nothing was really hard to find, the biggest issue was cost. But they are available.

Of the sets that I wanted only the Standing Liberty is beyond what I want to pay, so I guess the 1916 standing liberty is the key I won't get.

In New Zealand we have 2 big Key dates

1935 Threepence - Just 40,364 minted and the most scarce of all the circulating coins.


What-Is-The-King-Of-Key-Dates?
Not my coin and not my image

1935 Waitangi Crown - Just 1,128 minted and sold at 7/6 ensuring these coins were never hits with the public. 364 Proof coins and 764 standard uncirculated issue coins.


What-Is-The-King-Of-Key-Dates?
Not my image from Pinterest - Standard finish 764 coins


What-Is-The-King-Of-Key-Dates?
Proof coin (Image stolen off net and slightly modified) 364 minted.

Let me reiterate I DO NOT OWN any of these coins.

The costs are (NZD$) 1935 Crowns - VF $5k, EF $6k, UNC $8k, Proof - $10 - $15k (And rest of set $2 - $4k more)

1935 3d - VG $200, VF $500, EF $1k, UNC $2k, Proof $2k

I looked, couldn't find it unless I'm missing it. I'm not a professional numismatist, just a hobbyist. What constitutes a key date, mintage?

That tends to be part of the problem. We don't have a good definition of exactly what a "ke" or "semi-key" date is. Without that it is then hard to declare what is the "King key date.

I guess all my key dates are the ones I don't have.

My definition of a Key date is

In a series of coins and types (Like Mercury dimes, Walker Dollars, New Zealand Threepences, British pennies etc), a key date is usually the rarest one that is not a proof only/essay or pattern. Basically the date that circulated with the lowest number minted for that year (Or Mintmark in many cases) that is available to general collectors.

Good example, a 1933 Penny is not a key date as it was not really available but a 1951 Penny is - a 1913 V nickel is not a Key date, but an 1883 one is. For me my key dates for UK Halfcrowns would be 1905 as only 188k were minted and you can find them - but a 1952 Halfcrown is not, as only 6 exist and they are all patterns that never circulated and most would be privately owned by mints or museums.

A semi key is like the next 2 or 3 coins - sometimes you have a key date from only 4 different dates/mints of a coin like say an 1868 US 2 cent piece. On the other hand some series with hundreds of dates/mint tyoes/varieties may only have 1 or 2 keys.
