Other early Jordan cards have been going up for a while.
The 1985 Star Slam Dunk 5 x 7 is up about 30% since last year. One of the nicest looking Jordans IMO:
The 1986 Merchante has nearly tripled since 2015.
While I find the sudden run-up on the 86 Fleer to be suspiciously like the manipulated prices on the baseball RCs a few years ago, the overall market for early Jordan cards does seem to be legitimately up in a trend that long predated the surge on the 86 Fleer. In the case of the Star cards, prices are jumping w/o the help of the PSA registry since PSA won't grade them. As for me, since everyone is gold-rushing the early Fleer and Star cards I am picking up 1990s parallels instead to fill out my collection
Also might be worth grabbing some early Jordan team issued photos
These are often undervalued and misidentified when offered for sale.
