Finding all of those at once must have gotten your heart pumping....I imagine you'll be back to that area again. Cool recoveries.
Congrats on a nice concentration of old coins. I'm thinking you have two separate 2 coin spills that just happened to be in the same area.
Awesome finds! Seems more likely they were lost 50+ years apart, right? You never know! I saw a video of someone finding a copper memorial stuck to a buffalo nickel recently haha.
