FWIW, I’ve done things differently in this situation.
Knowing human nature as I do, I never turn money in like this.
I give the store, or where ever, my card and tell them I found something valuable and if someone comes in who lost something have them call me and if they can identify it, I’ll get it back to them.
I’ve known several cases over the years where the money went right in the clerk or manager’s pocket, who then denied anything was ever turned in.
But I’m glad it worked out this time.
