As your post doesn't mention anything about pricing, this really doesn't belong in the price guide discussion - unless you were wondering what it's worth. As for uploading pics - you can do so by going to the gallery, finding the appropriate area where you want the pics to go (in this case the error card museum), then click on upload at the top of the page. If you have a scan of the card, you can hit browse on the page that comes up, and find the file on your computer. Then scroll down and hit the submit button. It's as easy as that. Then when the image is up on the gym, you can link to that page of the picture and show everyone.
So are you asking what this is worth? I'd say about one and a half times what the original is worth.
