Don't worry.....be happy!
I would guess it is all up to how you like your coins. If you like them toned, I'd place it in a nice mint bag, then box it. Put it in the earth, or some other place that will stay nice and solidly frozen this winter

Then bring her out and lay her in the window sill for the summer. She'd prolly come out a beauty!
But if you like them white and shiny....them's the breaks! Just send it to me...I'll give her a good home
Whatever you do, don't redip her. You'll just damage her even more.
