I need help with an appraisal for an antique Capodimonte cup & saucer

This set of cup and saucer belonged to my grandmother and was recently passed on to me. It is in fantastic condition, and the mark "Capodimonte, Italy" can be clearly read on the bottom of each individual piece, along with the number 738. The cup has a completely golden interior, and the handle also has the same colour. The outer wall of the cup is intricately decorated with hand-painted pictures of very young boys picking and holding apples. The whole piece is also textured, with the boys standing in relief against the background. The same pattern repeats in the saucer, with the centre being completely golden, and the edge decorated with the hand-painted boys in relief. I would very much appreciate if anyone could help me determine the period of these pieces and how much they might be worth. Thank you in advance!

Good
