I'm just getting into penny sorting for my own personal use. Over here in Okinawa, I can get pennys just like at home, albiet I only have a few places to get them from. That said, I can sort all I want (I'm assuming), but I have to have a means to ship them home... so that boils down to 2 ways.
Either the shipping company will move all of my household goods when it's time, and save me a lot of effort on getting these coins home.... but those shipping companies usually refuse to ship 'money'. So that might not happen.
OR the option remains that I can ship them home via the postal service. If I do that, what's the best way to ship them without having the contents revealed? Loose packed? Rolled? Double vacuum sealed bags?
Surely you pros out there have a fool-proof way to ship safely.
