Thanks the the replys all ,appreciate your comments.
I think selling the coin and having to post is going to create to much risk for me personally, especially without insurance, potential of getting lost in the post etc.
If i found a buyer in Aus i may sell, depending on the premium it catches, it would be easy for me to fly to a location in Aus for delivery and receive funds.
And i agree with blucepheus, these coins are stunning.
There is the possibility of peeling the coin too to keep the funds secure, say if the secure location i keep it - burns down or has a extreme event (flood) at least i can keep the digital coin safe.
I'd really like to keep it unpeeled though, it gives it more beauty this way, it holds a secret, which makes it super special.
