Lost my Dell Win 10Pro USB Dongle

Lost my Dell USB Install Dongle, Windows 10 Pro. I can't find the stupid thing anywhere. I had it on my desk at home the last I recall, but now, POOF!!! I have a couple of Dell Laptops and even some Desktops All running the Authentic Win 10. They each have their own numbers (one think I like about Dell, they're on the system and I don't have to try to fat fanger the numbers in, LOL!) Anyway, is there anywhere I can get a replacement dongle? Also, anyone know how much they are?
