5 oz... Nice!!!! When this was minted i am sure it carried a large premium. I like these kinds of finds with the box and certificate. This is the time to grab the special’s. We had one counter person at our LCS that would hold onto extra nice pieces. Some times he would be in the back,and a young kid would be out front and he would say “no we dont have anything new”. I would have to ask for Robert and he would come out and fling something new on the counter. 🤫
