I think its worth it. I sold mine a few years ago for 15K It was in comparable condition but I sold it with one of those repro PF. I couldn't decide if should put the new PF in it or leave it original. The repro playfield looked a bit too new in my opinion. When I received the offer for it, I had to let her go.. I was happy and the buyer was happy. Here are some pictures of it: https://pinside.com/pinball/forum/topic/gottlieb-mermaid-price-check/page/3
