I've never tried before treat them gently. I just collect them and they all the time in plastic cases.
Try and tell us after how it is going.
Your order will be shipped in couple days (third batch on the way)
I guess I'm lucky to get two of each
One of each will make really good presents.... (I won't abuse the coins just treat them normally)
I'll be sure to say if they are extra sensitive in case I find out!
Thank you for the update!
