What is the value of a 1964 liberty standing quarter?

The last Liberty Standing quarters were minted in 1930. All quarters minted after that have the current image of Washington on the obverse. A 1964 Liberty Standing quarter would be a privately-minted fantasy piece with little collector value.

If you have a 1964 Washington quarter it's worth about $3.50 for its silver content. If you have a different coin please post a new question with additional details.
