3 Quarters - 1952 + 1962 + 1963 in a Paperweight

[vscience]

I'm giggling because I bought this paperweight for 10 cents. Funny thing is that it has 3 shiny new quarters in it. 1952 + 1962 + 1963. It made money sense to me.
Paperweight says: " MCA, Mechanical Contractors Association, Three Quarters of a Century of Progress, Chicago, Ill May, 1964". In your opinion, are these quarters worth more or less than 25cents each?

They are worth at least $2.50 each just for their silver content.
