A complete 5 coin 1964 proof set in original mint packaging has a current value of $30.00. The issue price was $2.10.
Sorry no US dollar coins dated 1964

Both coins have the same value of $5.00 in uncirculated condition
Silver U.S. coins dated 1964 or earlier are still legal tender at face value.
If the coins show any wear, value is about $2.00 just for the silver.
The coin is very common, most are valued for the silver only at about 5 dollars. 1964 was the last year for 90% silver coins.
1964 is the highest mintage and last year of all 90% silver Washington quarters, and most coins are valued only for the silver at about $3.00
With no rare dates they likely are only valued for the silver.
1964 is the first year of issue and the only year it was struck in 90% silver. The coins are very common. Even uncirculated coins are valued only for the silver they contain, about $12.00.
As of today, the value of the silver for each coin is: .50 = $6.23 / .25=$3.11 / .10= $1.25
U.S. quarters dated from 1943-1964 are 90% silver. These are common coins that are mostly valued for the silver, about $3.51 each as of today. The 1965 to 1971 are clad coins that are only face value.
Inflation caused the silver content of coins to be worth more than their face value so the US mint stopped making silver coins for circulation.
