Historic vintage card values over the years???

[1952boyntoncollector]

more and more historic cards are getting slabbed and the slabbed cards arent disappearing or getting in worse shape..

thus market will stay around the same except some of the current people interested are doing well in the economy the prices will rise..but eventually as less and less people are buying the cards, this lack of bid competiition will result in lower prices unless there are new people entering the vintage market......that shoudl happen when the kids growing up in the 1990s who really didnt collect cards become 40 years old or so....thats about 15 years from now.....the kids growing up in the 80s i feel are similiar to the kids in the 70s so that group should prevent the colllapse for the next 15 years...
