Hold onto your coins for dear life, fair market value coming to a reality near you in the not too distant future.
Personally I love coins. So many to collect, so many unique designs out there too. The first time I saw a Zombucks coin I just about fell out of my chair. And then the Canadian and Australian mint have so many unique coins they've been pumping out that the hunt is never ending. Same with the New Zealand mint, although Aussie and Kiwi coins are bigger and don't fit into standard coin snaps, which is a bummer because 40mm coin holders are harder to find for some reason.
Love the panda coin you got there, I have the silver version kicking around somewhere. Can't go wrong with RCM, they have the best silver refining process in the world, which means their gold coins are just as good because I believe silver is used in the gold refining process.
