Just like any collectible item, some snow globes gain worth over time while others do not. If you are interested in making an investment, the key is collecting the right type. Vintage snow globes, old original Disney character snow globes, and even a few snow globes that were originally advertising giveaways are now worth thousands of dollars. When collecting snow globes for more than personal pleasure, look for quality materials, quality of craftsmanship, a strong base, intricacy of detail, unique or rare models, and snow globes that are in pristine condition.
