I Found These At My Grandma’s House And Have No Idea What They Are

Old items at grandparents’ houses can be from completely different categories, for example:

Antiques or heirlooms (old coins, jewelry, utensils, tools)
Household utility items (vintage kitchen tools, sewing kits, sewing machine parts)
Religious or cultural objects (prayer beads, charms, incense holders)
Medical or grooming tools (old razors, syringes, massage tools)
Electronics or mechanical parts (radio components, batteries, adapters)
Collectibles or toys (marbles, stamps, trading items)
Each of these requires totally different interpretation, and guessing without seeing them would likely be wrong.
