Sometime in the future, anything thats less than NM will probably have no value at all.
This is just a passing thought, and I think its worth discussing. Were in the second junk wax era, and everything is being mass produced the way baseball cards were in the 90s.
Things like A/B/U have a ton of value because its basically impossible to get your hands on one at all, but in 10-20-30 years, every single card thats been printed since maybe 2015 has been stored in sleeves their entire life. Theyve been produced to hell and back, and everything from junk rares to commons have been kept perfect somewhere. I think that the market is going to be overrun with damn near perfect copies of everything, and anybody still collecting at that point will have no reason to buy cards that have even a slight bit of play on them.
Even cards that are truly rare like the Golden Smaug will be so well kept that collectors will be able to easily pass on cards that have a little damage, because 498 of them will have been kept in sleeves their entire life.
