Here's something else.
From what I've noticed working at my LCS is prices are kinda unstable. Due to the lockdowns more people are either rediscovering their interest in collecting, or getting into it for the first time. Due to the increase in interest and more interested buyers, demand goes up. On the other hand because of the lockdowns some people are downsizing their collections so supply goes up. Also, due to the lockdowns generally people have less "free" money to spend on coins which in some sub-markets are suppressing markets, while by contrast the high tier market seems to be thriving as high tier collectors seem to be taking advantage of the influx of high quality items to buy up what they can. Also due to the increase in metals prices across the board coins which have their value either completely or a large percentage derived from spot price have trended upwards in recent months. So the answer is a bit odd. Coins that are effectively bullion have gone up. Top pop coins have gone up. Scarcities have stayed the same, and common man's coins are unstable.
