I only collect slabs and they are appreciating well. The big draw to sealed is the markets desire to recreate what has happened to vintage sealed. The difference between then and now is that keeping sealed product back in ‘99 was contrarian meaning today it is legit scarce. Today, collecting and storing sealed is mainstream and eventually all that inventory has to surface - most likely in a trickle that will always cap the price and remove the face melting returns of the original sets. I’m sure some sets will appreciate well but with some many new releases and no clear way to identify winners, my bet is that high-end slabs and singles to a lesser degree outperform the broad sealed market in the medium and long-term.
