I actually got a coin with green tape on it too. They completely tore the package and wrapping apart, even discarding the flip itself, but eventually sealed the coin back up in bubble wrap and paper and sent it on. It was a case where the seller put the full description of "Ancient Roman silver denarius ..." on the customs declaration. Never again.
Green tape? Yeah, I'm familiar. Good to know my stuffing is safe! (part of an... "eclectic"... box of gifts from my mom)
