Potbelly Pig Charm Piglet Sterling Silver Pendant 4 Bracelet

Very nice vintage pig charms - traditional in nature with a secure jump ring. This one measures 3/4" wide. Love the corkscrew tail. It's stamped STER on the side of the belly - a good indication of older vintage pieces. Solid lost wax cast (not hollow) - See pic 3? I tried to shoot the underbelly - there are 8 nipples or teats shown - did you know a pig can have up to 16?? So how many piglets do they have? Best guess on this one 1960's era. Mint unworn condition.
