I don't know when you tested it or with what coordinator or if the coordinator charged you a coordination fee at the time (now paid coordinators are not allowed anymore) so, I cannot explain why you paid what you paid.
However, as I said, currently there is no coordination fee, only mining fee and it is right now 5sats/vb what is a reasonable rate. Here you can see a very recent coinjoin and its mining fee rate: https://mempool.space/es/tx/ec86a5f5d9cb9bb9fa8290ed0ed0af3a8cb7a6b3b76504dd09bbb6ebccb5b024?mode=details
