For many years I had one of those magnetic pinholders you get at the fabric store with a hole at the top, a clear plastic container and a magnet around the hole to keep the pins in (sort of). Mine was old enough it was lime green plastic, though I remember a lot of gold ones around that time! It worked okay, but seemed like it never held enough pins and if it hit the floor, the pins spilled out and had to be picked up by hand and stuffed back in the hole.
Then I was introduced to the magnetic tool bowl!
Check your local hardware store or automotive part supplier for a magnetic tool holder or magnetic parts holder. Costs less than $10 and is a wonderful addition to your sewing kit.
