I found this pretty interesting - got this in my mail a few days ago: Not too sure if it's valid to leave the serial number as it is though And those who is curious what year the penny is, it's 1951. Yes, it's a genuine copper penny.
lol no, I'm in Aus, not in the US. I found one of the lines to be interesting in the packaging: "Keep this lucky penny in a safe place, and present it to our servicemen to receive $50 Cash-Back* on your Plumbing Job" Oh well, now it looks like I'm advertising for them in a way
