Introduction

So, here is the fascinating world of bicentennial quarters, coins issued in 1976 in honor of the bicentennial of the United States of America. 

These coins are not just a part of history, they are real treasures for collectors and numismatists.

  • We will delve into their history, reveal their significance for the market, and learn about the different types and circulations. 

Are you ready to find out what influences bicentenial quarter value and why these coins still attract the attention of collectors around the world?

Bicentennial Quarter Types & Mintage

  • The 1976 bicentenial quarter coin, issued in honor of the bicentennial of the independence of the United States of America, has become not just a commemorative badge, but also a subject of keen interest to numismatists and collectors. 
  • Despite their apparent simplicity, there are two main types of these quarters, which differ radically both in metal composition and in circulation. 
  • These differences directly affect their collectible value and popularity. 

Clad Quarters 

The bulk of the bicentennial quarters were minted using a copper-nickel coating.

These coins, intended for everyday circulation, have the following composition: 91.67% copper and 8.33% nickel.

Visually, they look like ordinary coins, but a close examination shows that the minting was carried out at three different mints, each of which contributed to the total volume of issued copies.

Mint Marks

  • No mint mark = Philadelphia
    • As one of the oldest and largest mints in the United States, Philadelphia has made a major contribution to the circulation of bicentennial quarters. 
    • A huge number of coins – more than 809 million copies – were minted here. The absence of a mint mark is a characteristic feature of these quarters. 
    • They were intended for wide distribution and became an integral part of the circulation of those years.
  • “D” = Denver
    • The Denver Mint has also been actively involved in the production of these commemorative coins. 
    • His contribution of approximately 860 million copies is almost comparable to Philadelphia. 
    • A distinctive feature of the coins minted in Denver is the presence of the letter “D” under the bust of Washington on the obverse.
  • “S” = San Francisco
    • Unlike the previous two, San Francisco did not mass produce bicentennial quarters for circulation. 
    • Only Proof copies were minted here. 
    • These coins are distinguished by their high quality minting, mirrored surface and are designed for collectible sets and collectors who appreciate impeccable workmanship. 
    • Their circulation is, of course, significantly less than that of coins intended for circulation.

Silver Quarters

These coins, containing 40% silver and 60% copper, are distinguished not only by their precious metal, but also by their rarity. 

The Rare bicentenial quarter is almost impossible to find in ordinary circulation. 

They were not produced for everyday use. Instead, they were intended exclusively for collectors and were included in special sets and trial editions.

Only found in:

  • The total circulation of the silver bicentennial quarters is estimated at about 11 million copies. 
  • This number includes both Proof coins, which are characterized by high quality minting, and coins designed for Uncirculated collectible sets. 
  • These coins represent significant collectible value due to their composition, limited edition, and commemorative issue status.

How to Identify a Valuable Bicentennial Quarter

Check the Mint Mark

The mint mark (if any) is located on the obverse (obverse) of the coin, under the bust of George Washington.

No mint mark = Philadelphia (common)

If there is no letter under the bust of Washington, it means that the coin was minted in Philadelphia.

“D” = Denver (common)

Means that the coin was minted in Denver.

“S” = San Francisco (proof or silver)

Means that the coin was minted in San Francisco.

 Look for Errors

Doubled lettering/numbers (use a 10x magnifier)

Examine the inscriptions “LIBERTY” and “IN GOD WE TRUST”, as well as the date (1776-1976) using a magnifying glass. Look for signs of bifurcation or displacement of letters and numbers.

Partial or misaligned designs (off-center strikes)

Inspect the coin to make sure that the image is centered. If part of the image is missing or extends beyond the coin circle, it may be a misaligned bump.

Missing “S” mint mark (extremely rare)

If a coin looks like a trial one (high quality minting, mirrored surface), but it lacks the mint’s “S” mark, it may be an extremely valuable specimen. This applies only to trial coins.

Test for Silver (S-Mint Only)

This check is only valid for coins minted in San Francisco.

Weigh it

Use an accurate scale to weigh the coin. The silver quarter should weigh about 5.75 grams, while the regular one weighs 5.67 grams.

Magnet test

Hold the coin up to the magnet. An ordinary copper-nickel quarter will be slightly attracted, but a silver quarter will not.
