Yes, these are also my Grandmother's. Thankfully she's not dying, but she's moving and wants to seriously down-size.

I do think that it's probably better to sell them one at a time. Perhaps I will give it a go on some of the duplicates first before I mess up the "complete" collection.

I also found a store that's not too far from where I am. They can sell the whole collection on consignment, and it looks like they're able to fetch top-dollar on ebay. They give back only 55% of the net sale, but it may be worth it to get it done in one shot. http://vintagerarestuff.com/
