Would appreciate advice on best route to sell autographed baseballs passed-on to me

You have a nice collection of team balls. I have a few from the 60's and early 70's. And some have what is called Auction letter authentication. Which is when an auction house pays for a quick opinion. Then if you win the item you can go to authenticate it at a slightly reduced rate if you do it within 30 or 60 days after auction. I looked into getting a few team balls authenticated but cost is substantial $150 + for team balls with a couple hall of famers or stars.
Heritage Auctions sold a similar 1964 ball for $384 and you can look up other similar balls now that you know teams and years. But you can see at $150 + a ball it eats into profits. So it might be better to sell to an advanced collector who knows what he is doing.( not me I am just trying to help) but I do like your 1967 Mets ball.
Good luck

Thanks, that's what I plan on doing. Selling to collector rather than the time and money of having them authenticated.
