Hi Jon,
I'm very sorry to hear about your mom. My dad passed a few years ago and he left me his coin collection. I still have them sitting in a box because I am totally overwhelmed by the complexity of coin valuation and sales. I wish I had found a community like this one to help in that situation. As others have said, this is a great community who will go above and beyond to help you with this probably overwhelming endeavor. And they are honest and kind, so you don't need to worry about people trying to take advantage of you here.
I don't collect Tink, but I really do appreciate her and any cute pin really, so may be interested in purchasing some from you.
