I've been mailing coins outside of the U S for over 8 yrs. At our local P O, the clerk there always takes the package or padded envelope. I happened to go by a different P O and tried to mail coins to Australia. The clerk asked what was in the padded envelope. I answered, "Numismatic supplies." She then asked, "What's that?" I mistakely said coins. She punched her computer for awhile and showed me the screen: "It is illegal for coins to be exported.", or something like that. What the...... -I finally drove to another P O and was charged 1/2 of the postage (approx same size/weight) I was normally charged at my local P O. (For awhile, I had a hunch I was being overcharged at my local P O).
