They're both good coins in unc. The 50L would be worth about $40 but won't command much in XF. Same with the centime; they're common with wear.
The catalog does show a $10 value for XF but I doubt you'd find a buyer. They started making mint sets around '65 or so and after this there are enough nice specimens for the demand. The early coins just didn't get saved until they were almost all well worn. There are lots of moderns like this.
