Mint errors are one of the vital sophisticated segments of the uncommon coin market. We obtain dozens of calls and emails every month from people inquiring concerning the worth of a mint error. Many are simply broken cash that individuals in some way suppose are error cash. Most mint errors or misstruck cash are considered one of a form, there are infinite variations and worth will fluctuate from coin to coin. Regardless of the dramatic nature of many error cash, they’re usually value a lot lower than most would think about. Public sale data for mint error and misstruck cash are one of the best ways to review values for these enigmatic items.
Overdate mint errors of the twentieth century are extra well-liked and rather more collected. Many of those are thought of a part of the common collection and are extremely wanted. They’re additionally listed within the Information Guide of United States Cash (“Crimson Guide“) within the part for the collection. Many coin albums even have areas for these, which will increase demand, particularly in decrease grades.
The primary of those iconic mint errors is the 1918/7-D Buffalo Nickel. In The Full Information to Buffalo Nickels, the late David Lange explains how these have been created:
“In sinking a working die, two or extra impressions needed to be taken from a working hub. Between every impression, the creating die was taken to the furnace to be annealed, or softened, because the first impression brought on the steel to turn into workhardened. It was then prepared for one more impression. Amid the haste to supply new dies, a working die that had already been impressed with a hub dated 1917 was then both inadvertently or deliberately given one other impression from a hub dated 1918. The outcome was an overdate.”
The 1918/7-D is comparatively scarce, with NGC having numerically graded a couple of greater than 1,000 cash to this point. The overwhelming majority of those graded examples are closely circulated, and low-grade examples begin in worth at about $1,000. The shortage of high-grade cash might be as a result of the range was not seen by numismatists till the early Thirties. Selection and Gem examples are extraordinarily uncommon, with a single MS66 recorded within the NGC Census.
Precious Classic Silver Rarities
The following well-known overdates listed within the Crimson Guide are the 1942/1 and 1942/1-D Mercury Dimes. These two overdates are about equal in rarity with a numerically graded inhabitants within the NGC Census of two,288 and a couple of,048, respectively. The overdate for these are fairly dramatic and straightforward to identify, even on low-grade examples. This error coin continues to be cherry-picked by coin outlets shopping for 90% silver throughout the counter. Right here’s a superb tip for anybody promoting bulk 90% silver cash — verify the cash earlier than promoting them for soften worth. You by no means know.
The 1942/1 and 1942/1-D Mercury Dimes are additionally very uncommon in Selection and Gem situation. NGC has solely graded one MS66 and two MS65 examples of the 1942/1. They’ve graded a couple of extra of the 1942/1-D Mercury Dime in Gem situation, with three on the MS 67 stage. Each of those cash convey substantial premiums if they’ve full bands on the reverse. Oher than the 1916-D Mercury Dime, these two are by far the most costly cash of the collection in circulated grades.
Subsequent up is the scarce 1918/7-S Standing Liberty Quarter. Like the opposite cash talked about above, this overdate was not found till almost 20 years after the cash have been issued. By then, the very best probability of discovering one was by trying by way of rolls of circulated quarters. Only a few have been saved in Mint situation. The 1918/7-S Standing Quarter can also be one of many weakest struck of the collection. Full Head examples are almost unprecedented. Fairly a couple of are additionally seen with heavy conflict marks in Liberty’s robe.
Up to now, NGC has numerically graded 350 examples with out Full Head. Solely 20 1918/7-S Standing Liberty Quarters have been designated as Full Head, in response to the NGC Census. Clearly, the 1918/7-S Standing Quarter is the rarest of the cash talked about to date. Properly-worn examples begin at round $1,500 and go up quickly in every grade. Gem examples are extraordinarily uncommon, with the finest-graded coin at NGC being a single MS67 that bought at public sale in 2024 for $108,000. Not like the 1942/1 Dimes talked about above, I’ve by no means heard of a supplier discovering considered one of these in 90% silver. One necessary tip for getting an instance of the 1918/7-S Standing Quarter is to make sure the overdate may be very clear and straightforward to see. The resale worth of the coin can be impacted if the overdate is barely seen.
Gold Coin Overdates of the twentieth Century
The cash talked about above are all well-established collection with hundreds of collectors. Nonetheless, a number of gold points make up the lesser-known overdates of the twentieth century. These gold cash are all fairly scarce and underrated in comparison with the above “key” points.
The 1901/0-S Liberty Half Eagle is the primary on the record. This overdate is kind of apparent and straightforward to identify with the bare eye. NGC has numerically grade solely about 500 examples of this overdate — for comparability, they’ve graded 8,327 1901-S Half Eagles. The 1901-S Half Eagle is likely one of the most typical dates of your complete collection, however the overdate for the yr is kind of scarce. Surprisingly, the 1901/0-S Half Eagle sells for simply over soften worth in grades beneath Mint State. Selection and Gem examples are fairly uncommon, with simply 4 having been graded as MS66. In my view, the 1901/0-S may be very underpriced in all grades.
The ultimate coin in our research of “Crimson Guide” overdates is the favored 1909/8 Double Eagle. Due to the coin’s dimension, the overdate for this challenge may be very apparent and straightforward to identify from a mile away. The 1909 and 1909/8 Double Eagles are a really attention-grabbing pair of cash. Surprisingly, the 1909/8 Double Eagle is the extra frequent of the 2. NGC has numerically graded 1,757 1909/8 Double Eagles and simply 1,379 1909 Double Eagles. Gem examples are additionally rarer for the 1909 Double Eagle. It’s the one overdate challenge of the twentieth century with this distinctive distinction. The 1909/8 Double Eagle is one my favourite cash of the Saint-Gaudens collection due to the daring nature of the overdate. You’ll not have any hassle discovering an instance, and for cash beneath Selection situation, the worth can be near its soften worth.
For collectors searching for one thing completely different, a set of the above six cash would make an attention-grabbing mini-collection. The 1918/7-D Buffalo Nickel and the 1918/7-S Standing Quarters have lengthy been on the 100 Biggest U.S. Cash record. All of them have an attention-grabbing story, and most are very uncommon in Selection situation. The 2 gold cash additionally appear to screaming buys at present worth ranges. As at all times, we propose discovering the very best you may afford.
