Leaf pressed in 1860s volume

I discovered a leaf while processing a collection. This specific volume is a ledger from the 1860s. There is only light discoloration on the surrounding pages, luckily. Does anyone have any reason to value this kind of thing? Could have been pressed in between 1860 and now. The collection is not related to nature or science in any way.
