I’d love to have them.
You ar right about uncirculated to have some value. Though only some uncirculated have value and it really means uncirculated not touched.
Most likely will not have much value though can be loads of fun looking at history and the craftsmanship that has gone into the design of the older stuff.
In general only the gold and silver is worth its value i gold and silver. random non rare stuff coins go for a tenner or twenty a kg and notes for 50p or a quid if its somewhat decent. For notes only higher denominations of old stuff genrally attract some value but I guess you won’t have many of those if any.
