Dehumidifier is the best solution, but if you don't want to drop that much money then I'd try putting a tub of DampRid (this stuff http://www.homedepot.com/p/DampRid-64-oz-Fragrance-Free-High-Capacity-Moisture-Absorber-FG50T/100391308) near your collection. It works pretty well.
I lived on the Cali coast for a few years where the humidity was usually >85%. The mold problem was so severe that it would get into the walls (outside and inside) of my place.
