Looks like your little item(s) could use a clean-up (sometimes helps seeing marks/details) ... since they're not antiques , I'd just give them a hot water wash with dish soap & then get a non-metalic bowl & add hot water & a spoon of baking soda --- put a piece of aluminum foil (a little bigger than the item being de-tarnished) in the bottom of the bowl & set your (suspected) silver atop it ... should take just a min or two ; rinse well with hot water afterwards .
The one bracelet looks like silver-plate over copper (but silver often appears like copper or gold in photos) ... doing the above cleaning should/will reveal if any of your items are plated , Kevin_Bones .
I can't see for beans , from your images , though ... I'd just give the suggestion to check out some Taxco silver marks (major center of silverworking , South o' the border) sometimes a Taxco mark will draw a customer & a buck or 2 more !
