The four gold coins I added last year while gold was low. The American Legion set I bought the day of it's release at a early release price. The three 2016 .999 commemoratives from EBAY near the price of spot, which took some time. Not that I'll ever sell these, the half and quarter are already turning a small profit closing today at $1749.65. I'd call these a solid investment.
Sadly, nothing older like Coronets or Indians which are always on my list. Just not quite at a price I'm comfortable with. I think of myself as a smart buyer rather than the must have sort since I'm not out to collect a specific series to completion. Where I look to be is just below market average for the grade which is more challenging than first thought. So, that's my goal for this year. Old gold!
