There is somewhat of a market for selling replicas (if they're good enough) on Depop. I look around for Jordans there from time to time and some sellers will list replicas of high profile shoes like the Travis Scott 4's (or 1's, for another example), Bred Highs, etc. The replicas are expensive, but considerably cheaper than authentic pairs. They just say something like "price reflects authenticity/quality," or however you'd choose to phrase it.
Not sure if this is limited only to Depop or if it's happening on other reselling platforms, and I have no idea what to charge for em. I guess it depends on how good the fakes are... but I think there are people out there who will settle for a good fake over paying full resale prices.
