16 & 12 gauge vintage shells all lead

Cardboard shotgun shells  asking 20 bucks for it all 16 gauge x7 shot size 4,5,bb  lot number two 12ga x10 all high brass three slugs the rest is birdshot. Only shells with corrosion are the slugs. The other ones may have a little bit of a green tint to them but nothing that isn’t removable by  fingernail birdshot should be fireable -slugs  are a little iffy.  Recommended use is for display. I do think they would be fine, but I am not liable. Hard to tell with old shells local only no shipping must have a  pal always open offer/trades
