The 1982-P Washington Quarter, minted in Philadelphia, is an interesting coin for collectors due to its average value range. 

For coins in circulated condition, the value remains close to its face value of $0.25. However, the value can drastically increase to as much as $35 for coins in pristine, uncirculated condition.

This vast difference in value is attributed to the rarity of 1982-P quarters in top-notch condition, as well as the limited number of high-grade examples available in the market. As such, collectors are keen to acquire these pieces in the best possible state, driving up their value.

This particular coin---which fetched an impressive $10,200 at an auction in 2019---was graded as Mint State 68 (MS68) by the Professional Coin Grading Service (PCGS), indicating its near-perfect condition. 

A primary factor contributing to the coin's high value is the rarity of 1982-P quarters in such pristine condition. 

With only a handful of examples known to exist in MS68, it's no surprise that this coin remains a coveted piece among collectors.

In circulated states, the coin is typically worth around $0.25, while uncirculated examples can fetch up to $25. The 1982-D Washington Quarter is known for its strong strike and relatively higher mintage compared to its Philadelphia counterpart. 

Consequently, the 1982-D version is generally more available in higher grades, which accounts for its lower value compared to the 1982-P Washington Quarter.

The highest recorded sale for the 1982-D Washington Quarter was $4,320 at an auction in 2020 with a grade of MS68.

The 1995-P Washington Quarter is a sought-after coin among collectors, as demonstrated by its $3,600 sale price in 2019.

The 1995-P Washington Quarter presents an intriguing value range for collectors. For coins in circulated condition, the value remains close to its face value at $0.25. In contrast, uncirculated examples can reach values as high as $17.

This disparity in value demonstrates the significance of a coin's condition in determining its overall worth.

The 1997-P Washington Quarter showcases a similar pattern in value, with circulated examples holding a value close to $0.25, and uncirculated coins fetching up to $14. 

This coin's value is partly influenced by its attractive mint luster and overall quality. Collectors appreciate the 1997-P Washington Quarter for its visual appeal and eye-catching design, making it a sought-after piece in high grades.

This 1997-P Washington Quarter, boasts a unique distinction due to its grade of MS67+ from PCGS. 

While not as high as the MS68 of other coins on this list, the "+" designation indicates a coin that is visually superior to those within the same grade. 

This rare combination of quality and eye appeal resulted in a 2016 auction sale price of $3,525, reflecting the coin's high desirability among collectors.

The 1986-P Washington Quarter is another coin with a wide value range. In circulated condition, it is worth around its face value of $0.25. 

However, uncirculated examples can fetch as much as $14. The coin's value is derived from its mint luster and overall quality.

The 1983-P Washington Quarter, despite its lower MS63 grade, managed to fetch $2,596 at a 2016 auction. 

The 1983-P Washington Quarter holds a particularly impressive value range, with circulated coins being worth around $2, while uncirculated examples can command prices as high as $1,500. 

The high value for this coin, even in lower grades, can be attributed to the rarity of the 1983-P Washington Quarter in any grade. 

Due to weak strikes and overall poor production quality, very few examples of this coin exist in higher grades, driving up the value of even lower-grade specimens.

The 1989-P Washington Quarter presents a value range similar to other coins in the series, with circulated coins valued at around $0.25 and uncirculated examples reaching up to $14. 

Although the 1989-P Washington Quarter is not considered a key date or a particularly rare coin, collectors still find value in high-grade examples. Its mintage of over 900 million coins means that it is relatively abundant, but finding examples with exceptional eye appeal and sharp details can prove to be a challenge. 

For this reason, collectors are willing to pay a premium for 1989-P Washington Quarters in top-notch condition, making them a worthwhile addition to any collection.

With a 1989-P Washington Quarter graded MS67, it is no surprise that this coin achieved a sale price of $1,955 in a 2007 auction.
