Insurance: If you are purchasing an expensive item, I highly suggest you insure it at the full value. The USPS is highly dependable, until they are not!
Combined Shipping: I do combine shipping at a rate of .50 per additional coin until the value reaches the amount equal to a USPS Flat Rate Priority box and at that point will pack as many coins into the box as can safely be sent. Please let me know if you are purchasing multiple coins and then let me know when you are done and I will send you a combined invoice. If you don't wait for the combined invoice, I will still combine shipping and send you a partial shipping refund!
Positive feedback: Once you leave it, I will leave it! (I tried it the other way and nobody seems to reciprocate)!
