15 old religious pendants 3 crosses

I’m not really sure what these are worth but I know they’re old and most of them are in pretty good shape. I’ll sell as lot or individual pieces but the price I’m putting up is for all of them. Someone please message me and tell me if I’m way off so I don’t rip anyone off or get ripped off myself. I do know this only 3 of the medallions are magnetic and one of the crosses is. The rest are either silver, plated silver, white gold or aluminum. That’s why the price is kinda hard to come up with on this but I’ll take any info I can get even if you’re not interested in buying. Thanks.
