Heritage has responded to my inquiry that this is a score board jersey.

They said, "Scoreboard did promotions with game cuts from these style jerseys so that certainly was a consideration before we accepted them for auction. However, the Strawberry shows both pilling and sweat stains in the collar. It also came in from the most well-known Mets collector in the hobby, so we were comfortable with running it after it was reviewed."

Thanks to Chris Ivy for the explanation.
