There were metal cylindrical coin banks in which you slid the coin in and a screw on the top would secure the coins and push the bottom out when full. The screw scratched the coins. for example see this eBay auction: http://www.ebay.com/itm/Vtg-The-B-R...k-Dime-Tube-2-3-4-5-00-capacity-/191623686980 or http://www.ebay.com/itm/Vintage-1950s-Be-Thrifty-Tube-Dime-Bank-in-Original-Package-/371210599996
Oh, wow. I've seen that mark on many coins myself, but the only explanation I ever seemed to hear was that someone was using it to set up a lathe or other tool. I'd never seen one of these banks. Thanks for posting it!
One of the known 1894-S Barber dimes was damaged this way, although I guess it displayed other issues/damage as well.
My answer for these directly relates to coin wrapping machines although, given the size of the OP's quarters, I'd have to go along with the "Coin Bank Tube" as the correct answer. On smaller coins, the scratches near the center are from coin wrapping and as the coin gets larger, the circular scratches move out toward the edges.
These are dimes. I pulled most out of my junk silver. As far as the bank's value, one was posted for sale for $22. Filled with silver coins it would be worth $50 at least because silver is really low. I know the coins are damaged, just wondering what caused that type of damaged which has been answered.
Not really. The quarters and halves say IN GOD WE TRUST rather than UNITED STATES OF AMERICA on the obverse.
Huh, I just noticed that. Halves and Quarters have "United States of America" on the reverse an eagle, along with the denomination and "In God We Trust" on the front. Dimes have just the denomination on the reverse in the middle.
