1800s silver register in Baltimore on Antiques Roadshow

This person had a silver register that showed all silver purchases and sales at a store in the 1800s. I think the register spanned 30 yrs of transactions. They valued the book at $5-8k. There was even an item in the register that the appraiser had in his current collection!
