IMHO, large multiples are cool but large items are hard to store, and harder to sell. These issues are on the fence as "classic era". They make it under the date but its not like having a partial pane of banknotes. Unless the design is a se-tenant, there's no reason to keep as is. They're not full panes. I would keep the plate blocks, maybe 3x3 and sell off the rest......just my 2c of why I mentioned the PB pricing.
