I am submitting my first 5 coins to PCGS this week, and I am hoping someone on our list will give me a few tips on things to avoid, how to package the coins, send them USPS, UPS, Fed Ex, etc? Should I also use delivery confirmation? I will be paying the fee for the 21 working day 'Regular' submission timetable. I went to the PCGS site and all I could find was to package the coins so they will not get damaged. I may have missed this information somewhere else on the site. Thank You, Jim
