Tring to figure out if an unused, first generation (2016) , factory Sealed IPad Pro, 9.5" , 128 GB might have a greater resell value than a same model that has been used but in good/excellent condition. Specifically, wondering if because it is first gen and factory sealed - and if that has some additional value ? Also have an factory sealed Apple Pencil as well . Online resell sites are quoting under 100.00 for a used one in good condition. Thanks .
