Yes, from your description it sounds like situation where the hole was put into it in order to allow it to be worn as
jewelry. This seems to be a fairly common occurence, especially with less expensive/more common
LRBs such as your
Gloria Exercitus. I've got a couple holed coins myself. They can often be picked up at a discount to otherwise similiar pieces.
A lot of times these coins will be worn almost smooth from wear.
Warning: even though coins were worn as
jewelry, the last time I bought a coin at
auction, my wife found it in the mail and I attempted to pass it off as an
anniversary gift. The results were predictable and I would not recommend anyone else try this.
