The 1970 Washington quarters made in the Philadelphia mint are still very much in circulation today and are worth their face value or more depending on the condition of the coin.

The Philadelphia mint produced 136,420,000 instances, and there’s no mint mark on the quarter. It was produced in a very large quantity about 50 years ago, and that’s why it’s a common coin even today.

The downside of this is that in circulated and fine condition, they’ll not be worth much. But if you have them in uncirculated condition, they’ll be worth more than face value, although not considerably more. In MS60 grade, the 1979-P quarter is worth about $1 or even less, but in quality grades like MS66, it can be valued at about $60.

There are very few 1970-P quarters in MS67 grade and above, but if you happen to find one, it’ll be worth hundreds of dollars at least. However, if your 1970-P quarter has a grade of MS67+, it’ll be valued at about $2,750, according to PCGS.

The only instance, when you’ll get real money from the 1970-P quarter is if you find an error variation.

The 1970 quarter has no silver content, rather its composition is a nickel jacket over a copper core.

1970 “D” Washington Quarter

Denver mintage produced 417,341,364 170 quarters, and that’s quite a lot! This was the highest quarters minted that year, and they are easy to find, making them worth just a little above face value.

When coins are minted in large quantities, they lose their uniqueness and value. The worth of a coin is usually tied to its rarity, so if you have a common coin, there’s a high chance that it’ll not be worth anything meaningful, and the quarters minted in Denver isn’t any different.

A 1970-D quarter in MS60 grade won’t be worth more than $1, and you can even buy it for less than that. For an MS67 1970-D, you can get it for about $70.

1970-D quarters with gem quality grades like MS67+ and MS68 are both worth $450 and $2,750 respectively.

According to PCGS, a 1970-D quarter graded at MS68+ is worth $10,000, which is quite a leap in value from those in MS60 grade.

Yes, it might be wishful thinking, and very unlikely that you’ll have an MS68+ 1970-D quarter in your change jar, but it wouldn’t hurt to just properly check. There are lots of rare coins, and you never know what you might find.

1970 “S” Washington Quarter

1970 “S” Washington Quarter

All the coins minted in San Francisco in 1970 were proof coins, and they were 2,632,810 quarters in total.

Proof coins are usually struck on unique planchets, resulting in their glossy finish and clear details. These coins are worth more than face value because they were specially produced for collectors who bought Proof sets.

You might expect them to be worth a fortune, but on the contrary, an entire set of proof coins can be sold for less than $10. For instance, a 1970 – S proof Washington quarter graded at PR69DCAM is worth $455.

In 2007, at the Heritage auctions, a PR69DCAM 1970-S quarter was sold for $2,760. The proof coins designated as CAMEOs (CAM) are more valuable and that’s because they have an ice-like design and glossy finish. Coins designated as DCAM (designated cameo) have an even higher value because they have a stronger contrast.

There were lots of errors in the San Francisco mintage, and luckily, they are currently worth a sizeable fortune.

The most valuable quarter that every coin collector talks about is the 1970-S quarter struck on a 1941 Canadian quarter. Sound far-fetched? Well, it isn’t.

This coin is a property of Mike Byers, and according to him, it’s the most fascinating error to be made, and it’s worth $35,000.

History of the 1970 Washington Quarter

Washington quarters were first produced in 1932, although before then there had been a mintage of other quarters.

Prior to 1965, the composition of quarters was 90% silver and 10% copper. However, as a result of the high cost of production (the rising price of silver), the U.S mint started the production of quarters using copper-nickel alloy. This new composition made the coins less valuable as a metal, but on the brighter side, it was a more practical and durable option.

The 1970 Washington quarters were produced in three U.S. mint facilities; Philadelphia, Denver, and San Francisco.

Each of these coins measures 24.3 mm in diameter, with a weight of 5.67 grams. It also has a reeded edge, and this was not done for the sake of aesthetics, but to curb the fraudulent activities by individuals. The reeded design was introduced in the 17th century when coins were made with 90% silver. People usually filled the edges from the coins because they were made of special metals (silver), and this in turn reduced the weight of the coins, and merchants would have to use scales to weigh silver coins before accepting them as payment.

So, due to the reeded edge, you can easily detect when a coin has been clipped at the edge.

The reverse of the 1970 quarter coin was designed by Flanagan, and it depicts the image of a bald eagle in flight. On the observation of the coin, there’s the portrait of George Washington which was also sculpted by John Flanagan.

1970 Washington Quarter Grading

Coins are usually graded based on appearance, and the 1970 Washington quarter isn’t any different. Your coin can be graded on a scale of 1 to 70, with 70 being the highest pristine state.

Having a 1970 quarter with a grade of MS70 is very impossible, because even after production, coins are stored in bags, hence they are very likely to get scratched.

Your best chance at getting a coin that’s relatively close to MS70 is the 1970-S proof sets because these proof coins were stored with utmost care. Some proof coins have been graded at PR69, and that’s the best you’ll get.

About 100,000 of these error coins were produced before the mistake was discovered. You might have a chance at finding this error coin in your stash of change. While it might not be as valuable as the 1970 DDO error, it’s valued at $30 to $350 depending on the coin’s condition.
