How to price a mixed lot
Dealers and private sellers usually price junk silver one of two ways: by the total silver weight, or as a multiple of face value. The ledger gives you both — the pure silver ounces in the lot, and the face value they add up to — so you can check either quote against the metal.
For US 90% silver, a dollar of face value in any mix of dimes, quarters and halves comes to roughly 0.715 troy oz. That's the number to sanity-check against: if someone quotes "20 times face", you're paying 20 × $1 for about 0.715 oz of silver, and whether that's fair depends entirely on spot that day.
