My friend has one... a hole was drilled into each east and west “third side” reeding so it would spin inside the round holder it’s in which is attached to the keychain fob, from Montana. It’s also silver, and has a large over small LIBERTY-T. I looked because of that and learned there was a transition of the LIBERTY-T beginning in 2007.
Post your sources. That’s how research works, you post your sources so others can validate. As of now, we have to take whatever you say at face value. You want people to take you seriously? Post your work and post your sources.
Luckily, I am a live in personal assistant for my friend. I asked her to see the quarter again so here it is. A transitional left over silver planchet.
Imho, thank you for sharing the plated coin. When a coin is replated all sorts of anomalies can show up.
