Pirates / Forbes Field piece ?

Several years ago, I bought a large collection of cards and a few items of memorabilia. Included was this 4"x3" piece of slate, which measures about a half inch thick. As you can see, it has a Pirates logo centered in the middle, and then was covered by a clear lacquer. The guy who sold it to me said it was a piece of Forbes Field. Didn't think much about it, as it wasnt one of the items I was buying the collection for.
In any event, I came across it today. I'm not familiar with collectibles like this, so I was wondering if there is some way to authenticate it, or does some one know if it is legit ? And is this thing even worth anything ?
Thanks in advance ...

<< <i>They moved out of Forbes in the middle of the 1970 season. I'm not sure if that logo is that old. I could be wrong, but I associate that logo more in the mid 70s. >>
mlb.com says it was used from 1966-1987.
