Hey Antonov, welcome! Reselling art can be tricky. Galleries usually check provenance, authenticity, and condition. If galleries are turning you away, it could be a few things: missing documentation, doubts about authenticity, or the work not fitting their current collection. You might want to start with online platforms that cater to collectors, like auction sites or vetted art marketplaces, and make sure you have clear paperwork for each piece.
