I received the email regarding a partial printing plate from the Harris Printing Office engravers and this item has a likely value of $10 to $20 or more. This item would be best sold on eBay or another similar site with the actual note or at least a picture of the note this stamp produced. Very neat and interesting piece, but not much collectability for these type of items.
Thank you,

The idea of selling on ebay - if you were to sell it - with a photo of the note is a good one. I think with a nice write up and photos you would do better than his estimate.
I wrote to Heritage once about an item and they were very wrong about it so while they are professionals and do know their business they can make mistakes too.
But it is difficult to predict with a piece like this IMO.
