If you know what to look for, some coins that appear commonplace might have significant value. The 1975 No-S Proof Quarter is one example of such a coin. With some selling for almost $4 million, this rare coin has turned into a collector’s paradise! We’ll go over why this coin is so precious in this post, along with how to tell whether you own one.
What Makes the 1975 No-S Proof Quarter So Special?
A limited edition of the standard 1975 Proof Quarter is known as the 1975 No-S Proof Quarter. Because the mintmark, which is typically used to indicate where a coin was created, was accidentally left off, it is unique. Because of this uncommon error, it stood out and eventually rose to become one of the most desirable quarters for collectors.
How to Identify the 1975 No-S Proof Quarter
1. Look for the Missing Mintmark
U.S. coins typically bear a mintmark, such as D for Denver or S for San Francisco. Nonetheless, a small number of 1975 proof quarters were produced without the S mintmark, which makes them extremely unusual. Your 1975 quarter can be worth a lot of money if it is a proof coin without a mintmark.
2. Proof Coins Are Shiny and Smooth
The coin’s surface can also be used to identify it.Unlike conventional coins, which are more matte, proof coins are manufactured using unique procedures that give them a smooth and shining appearance. Your 1975 quarter might be a proof coin if it is very shiny.
3. High-Grade Condition
If the 1975 No-S Proof Quarter is in poor condition, its value is significantly higher. A well-preserved quarter will be worth far more than one that is worn down or scratched because collectors would pay top dollar for coins that are in almost pristine condition.
Why Is the 1975 No-S Proof Quarter Worth So Much?
This 1975 No-S Proof Quarter is extremely rare, which is why it can sell for about $4 million. There were only ever a few hundred of these coins produced, and many of them were destroyed or lost over time. For the opportunity to acquire one of these rare coins, collectors are prepared to shell out enormous sums of money.
You could be holding a $4 million treasure if you have a 1975 Proof Quarter without the S mintmark. Look for a proof coin’s smooth surface, exceptional condition, and absent mintmark. You might be in possession of something really precious if you possess one of these uncommon coins!
