Our side yard use to be full of clad coins probably from the previous owner. My daughter got one of those kids detectors when she was five years old. Her favorite thing was to detect that side yard. She is now thirty and still talks about it. Women are just attracted to money.
I'm sure your daughter will have a blast with it. My daughter never had an interest in her own detector, but always went with me as a youngster, and was very excited to see what came out of the dirt. She will be 33 in a few weeks, and she still wants me to send pictures of the items I find. You will make some great memories with your daughter and her detector.
