It is absolutely safe to mail your items to us. We recommend that you get a tracking number to go with any shipment you send us.
WARNING: Do not send coins in a plain white paper envelope-the envelope will tear and the coins will be lost. If sending coins and bankotes that weigh over a pound we strongly recommend using a flat rate box from the USPS. If it fits, it ships, for one flat rate regardless of the weight(up to 70 pounds).
