Thanks for your soapbox rant as you probably seen I can rant a lot myself! 😂💥
I think what we are seeing is the maturation of the collector market for certain collections, in particular Casascius and Lealana and possibly Satori and the likes of Crypto Imperator - these coins are gaining acceptance by the "mainstream" collector community as part of the historical record.
When this happens, prices rise because a limited quantity of coins suddenly becomes more widely recognized with a much larger pool of buyers. At the same time, we can expect premiums, especially for non-funded pieces, to stabilize to a (hopefully rising) dollar value as opposed to the BTC-denominated value we use here.
On the heads side of this, this can mean that the earliest coins become increasingly difficult to acquire for non-whales. Unlike a Bitcoin, you can't buy a fraction. Its like this with art, gemstones, and other rare coins or stamps.
On the tails, as the most sought-after items move into the larger and more moneyed mainstream market, new entrants and smaller players can purchase newer collections that still come from within this community - in hopes that in 10 years, they too might command ever-larger premiums - something that is still true in the traditional coin and stamp world where many collect new releases instead of speculating on historical pieces.
The reality is that many collect things not only because they are interesting, but because they are rare and desirable - like bitcoin itself - which then makes them even more difficult to get. Almost every collection gets sold eventually, if not by the collector than by their estate - which is already happening in our space.
