29) Sell your archive?

I know that most mail-artists that have been arround for decades have build up quite a collection. The best pieces they keep, other things they recycle. The 'garbage' is dealt with (or not). That leaves you with a problem of a growing collection that takes more time and is getting valuable. What do you think of the options:

1. Sell it to the highest bidder.
2. Arrange a museum of organisation to invest in currating the collection

And what to do when no-one wants the collection? Leave if for the next generation to decide on?
