The ANACS website mentions that one has to submit coins in Mylar flips. Some of my coins are in Airtite capsules, and others came in stapled cardboard squares, which I would prefer to keep in while being shipped. I would prefer ANACS open them once they receive them.
The flips seem like they could cause marks to the coin pressing against it, and the hologram could stick to the plastic flip.
Has anybody sent a coin in something other than a mylar flip to ANACS to be graded, and if so, was it accepted?
Yeh, I send them in Coin Capsules or even plastic ziplock bags.
They just dont want you to send it plain in an envelope.
