I made a reddit thread a while back about a coin set I had:
https://www.reddit.com/r/Bitcoin/comments/5lvjjr/check_out_my_casascius_1000btc_gold_coins/These don't have BTC in them but they are my most prized possession.
User throwawaydev400 made an offer I couldn't refuse to sell him 1 coin. We agreed on a price of 14 BTC about a month ago. We met in person today for the trade. And amazingly BTC price just broke gold parity. What a momentous occasion.
Thought I'd share.
EDIT: Currently selling for 14 BTC
