The amount of silver that would be worn off because of the coins rubbing together would be insignificant unless they did this for a significant length of time.
Hi, suppose i just store my silver in just a regular container in contact with each other out of carelessness and they eventually scratch themselves throughout time. I do believe that silver is around $25 a troy ounce. As a collector's item, the value of silver will obviously go down w/ wear and tear. But will the value of the actual silver as it is be really adversely affected?
