Here are the piece values of a few engines and players computed by regression analysis predicting game outcome based on piece balance. The value of a pawn is fixed at 100cp. The method is explained here: <https://www.chessprogramming.org/Point_Value_by_Regression_Analysis>

SF piece value analysis was performed using 60k STC games ran on fishtest with no adjudication and from UHO pgn book. (id:646b64e50db5177f2b772a5b) The values of piece combinations can be calculated in the future from the extracted piece balance data attached (rightmost column is game outcome, first 5 columns are piece balances in order from pawn to queen)

If anyone would like their own or other players/engines piece values to be calculated, they can provide a pgn or a link to a chess.com/lichess account.
