$3.00 just for the silver.
Any quarter from before 1968 was made with silver. Generally, unless your coin is in mint condition, your coin will be worth the current value of silver.
A 1970 US quarter has no silver, so it has no silver value.
At the time of writing, a US 90% silver quarter (dated 1964 or earlier) is worth $5.55 for the silver content. A Canadian quarter dated 1920-1967 80% silver quarter is worth $4.63, a Canadian quarter dated 1967-1968 that is 50% silver is worth $2.89.
Assuming the coin is circulated, the 1947-D Washington quarter is a high mintage common date coin, so if the coin has any wear the value is for the silver about $5.00.
