A crock pot? Does that do a good job storing them?
I'd probably end up the same way (seed swap). Sometimes I just want to get rid of old seeds so I throw them out in the soil and it's do or die. (I have a lot of growing area). Like this year I have one 3' x 50' row that is my "nursery" row and I planted a lot of old seeds there. Some are coming up, some not. And I only have the order of planting scribbled on a piece of paper. IF I lose that paper, until they are big enough to be identified, I'm sunk. And I would never know what DIDN'T come up!
