Goebel hummel figurines
When my 86 year old grandmother died in 1980, she left for me 5 hummel figurines by Goebel that she'd collected in her lifetime. They all have the Goebel mark and numbers on the bottoms. I know just the basics about how the hummel figurines got their start, and clearly don't know enough to determine whether or not these are of any spectacular value. What is the best resource to determine if they have any value at all, and if so, where would you recommend I try to sell them?
