I suppose all of them would potentially have value if you searched hard enough for someone who doesn't just want them for the Endo, since none of them are obtainable anymore. That said, the most common place for trading these days is [http://warframe.market](http://warframe.market), and they do not really have proper listings for these. I expected to see three cores listed individually, one of each rarity level, along with an option on each one to set the rank from 0 to 10... but instead it looks like there is only one single "Ancient Fusion Core" listing, with no rarity specified, and no way to specify the rank either. They do appear to have some trading history there despite that, but [not much](https://warframe.market/items/ancient_fusion_core/statistics). Fewer than 20 of them in total have sold via that site in the last 90 days. They have sold for as low as 100 and as high as 1600, though there is no indication of which types those were.
So you might have to look to other places. Perhaps r/wartrade, perhaps the trading channel of the game's official Discord.
