I recently found my snow globe collection in my fathers garage from when he moved 9 years ago. To my amazement I have this Feed the birds snow globe. I looked on ebay and found that one sold for $910.00. I'm debating on selling mine. Is anyone familiar with this snow globe? Is it something I should hold onto and pass it down to my kids? One website called it the wholly grail and it rarely comes up for sale. Any feedback would be greatly appreciated. Thanks!
