2 Bucket Listers 10 Feet Apart (Morgan & Seated)

I was at an old 1895 high school. I figured the day after graduation I'd come out and check under the bleachers of the football field for any fresh drops, but when I got there a guy was already detecting and just finishing up. He told me there wasnt much, he had checked under the bleachers already and just finished up the field. The week before I had checked those bleachers and found a rosie, a wheatie, and a 10k black hills gold ring. So I went under the visitor bleachers and did a couple passes through the field anyways, found 3 pull tabs in a row and decided to walk up to the soccer fields since I hadn't hunted up there yet. Walked about 30 feet off the field and was in a little dirt area near the football scoreboard, hit a 90-91 on my AT Pro and at most was thinking it'll a silver quarter or something. After digging through hard pack and some good sized rocks I saw a big eagle staring back at me and I just sat there stunned, speechless for a minute. Only thing I can think of is the hard pack/rocks may have deterred someone from digging it because that school has been hunted TO DEATH from what I've noticed.
Flash forward to a week later and I'm doing the same thing, walking from the football field up to the upper area and as usual, had my detector on while I walked in case I missed anything. Sure enough, I hit a 79-80 not more than 10 feet from where I found the Morgan, showing 2" depth. So I get down and there was a fairly fresh gopher mound, and 2" down an 1876 seated dime. Gopher probably dug it up for me (what a nice guy!). Shes slick but man its proof that people leave stuff behind. I went back yesterday with no luck, gonna try some less obvious spots of this huge school.
