My offer still stands, 1920 to 1950 coins, I will pay for shipping, charge me for counting and rolling.
You don't have to melt down the coinage yourself. Just take it to the local coin shop and trade it in for the metal content. Pre-1964 coins are 90% silver. One ounce of Pre-1964 coins = .9 ounces of silver. Five quarters = about an ounce = .9 ounces of silver. Silver is roughly at $7 an ounce. $7 x 0.9 = $6.30 for five quarters, or roughly $1.26 each.
That's just the silver value. There may very well be some XF/AU coins in that hoard. XF isn't great, but in some select coins it's better than the value of the silver content.
One time I was at the convenience store, and the counter person asked if it was ok to give me change in 50-cent pieces. Somebody paid for gas with them, and she didn't have a place for them. Money is money, so I didn't care. I got about $3 in coins (I forget exactly), all pre-64. I paid for gas and beer and came out ahead! How often does that happen?
