Key date? there really isn't one but the 2014 has the lowest mintage at 665,100 which is still plenty to go around. The 2018 mintage is at 550,000 but the sets are still on sale.
What give, is new issues, especially if mintages seem lower than normal or there is some other reason to hype the coin, prices shoot up. Then over time the hype dies off and prices tend to fall until they are in line with availability. The 2001 was hyped to high prices back then and has since dropped back to an average price, The 2012's were hyped to high prices when the Mint ended sales earlier than usual in the year and many people who had been waiting till the end of the year to order sets got shut out. That caused an unusual demand and high priced even though the mintage isn't unusually low. The 2012 set is still basking in the "rare set" myth and prices are still up. In the long run though I would expect the prices to eventually fall and that 2012 proof NA to drop to just a little above the other common dates.
