you could always store it here if its "real" silver.
Even if you don't have real silver, this is a nice light lock box that fits nicely in this cubby. It is anchored to the floor. There is two pieces of 5/8" plywood underneath it so the door would open.
If anyone is interested it is a SentrySafe and only weighs 13 pounds.
Prime price is $54.
The nice thing about Centry Safes is that if you lose the key and the battery is dead, you can get another key from SentrySafe just as long as you keep the safes serial number so you can give it to them. Unlike most other cheap safes where if you lose the key, your cutting the safe open.
