Looking at what you managed to photograph peeping out of the peanuts, I can tell you for sure that this is Waterford Glass and circa 1970s - 1980s vintage and in one of their signature cut glass patterns called "Lismore" named for the famous Irish seat of the Dukes of Devonshire at Lismore Castle, located near Waterford in Ireland.
Also, I'm fairly certain this is the eight arm version that should look like this:
As for value, your chandelier, once re-assembled and hanging on display, would sell at a good antique auction house in the range of $650 - $900. It has a full retail value of $2000, which is also the replacement value for insurance purposes.
As far as selling is concerned, unfortunately Memphis is something of a desert when it comes to good antique auctioneers. Your nearest one that would be appropriate for this piece would be:
4872 Hwy 64 East
Selmer, TN 38375
or Northgate Gallery auctioneers in Chattanooga, TN, http://www.northgateauctions.com who sell a lot of chandeliers.
Having said that, selling to a local antique dealer or vintage lighting retailer is certainly worth considering.
I would contact Southfront Antiques,(###) ###-####
374 S Front St, Memphis, TN 38103,
and ask them who the local vintage lighting dealer is. They will know. This is the person to talk to, explain you are going to sell the chandelier at auction and offer them first refusal. They will usually pay the low end of the auction estimate if they are interested. This is probably the easiest way to go, because it requires little travel and no transport headaches (they will collect for free, auction houses usually have a collection charge) and no auctioneer's seller's commission.
And finally, but as a 'first' resort, there is always Craig's List, where you could price this piece, initially, at somewhere between $1000 and full retail. It's surprising how many antique dealers -and amateur collectors- there are keeping an eye out for quality pieces like this being listed on Craig's List. If you are antsy about strangers coming to the house, just arrange a third party venue at the local Walmart parking lot, or similar.
Hope this helps!
