I have a 12 place setting plus serving pieces
set of Noritake Lismore that has been In storage for over 50 years

I would like to get some idea of it's value

Check Ebay. Quite honestly, it has minimal value except to a collector of that particular brand and setting. Not many new families have china place settings. A couple of years ago, I had a difficult time selling my mothers 1939 Noritake china

I checked ebay - not one listed recently has sold.
Plus, the sellers aren't asking a lot per piece. That means that shipping will be more than what they might sell for. Shipping what you have would be an enormous amount of time, supplies, and postage.

Your best bet is an ad in your local paper, or a local consignment shop.
