Help Getting My Gold Back Home?

G'day, you'll need to consider the law where you are; where you're going; and anywhere you transit.
In Australia, it is legal to import and export cash, but if it exceeds Oz$10,000 in value, then it must be declared. This includes gold and foreign cash. If one is caught; then forfeiture, a fine, and jail, are possible outcomes.
This law, copied from a USA precedent, is intended to hinder money laundering, and I'd be surprized if most other countries didn't have similar laws.
The additional problem with gold coins would be that the aviation authorities probably have rules about carrying potential projectiles on board. Nowadays, they won't even let you take a bottle of water on ...
Have you considered sending the coins by registered post ?

If you don't mind having them out of your site, I think I would start mailing them to myself. I would imagine you have friends or family that you can start sending them to one or two at a time.

If you do put it in your hand bagage then you should take it out and had it separately to the staff at the x-ray machine.

Gold is very dense and shows up immediately as solid black on an x-ray - if you just leave it in a shoulder bag and let it pass through the x-ray without notifying the staff about it you may find yourself the center of a minor incident.

I did this a few years ago with some bullion I was bringing back from London for a coin fair in Dublin a few weeks later.

They were not impressed - there was no issue with the value of the gold - but it looked like a grenade (or something that worried the guy on the x-ray monitor) and he hit the alarm button before asking me what I was carrying. I did get on the plane - but only just.
