This was mentioned long ago, but it seems like some renewed interest among some speculator groups are trying to revive this after the release of Black Panther #15, where a Symbiote attaches to Killmonger.

This first happened back in Black Panther #2.

You might still find Black Panther likely at your local shops. It seems to be selling around the $10 range.

There is still a 1:25 variant as well, which is hovering around the $35 range it seems for secondary market prices. If you can find these for cheap, could be nice grabs to flip for profit now or hold for the long term gamble.
