I can answer without photos.
This is an Italian silver-plated (not sterling) egg cup made by Wellner Firenze, a German run company in Firenze, Italy
with this mark having been used in the 1930's. The company made restaurant, hotel and cruise ship ware, so the monogram
of CH on the piece is the mark or logo of the hotel or ship that the piece was made for (unknown).
This egg cup would have a value of 30AUD retail.
You can read more about the company and the origins here- http://www.ascasonline.org/windowGIUGN61.html
Some sites that I recommend for selling are Gumtree.com, Traderoo.com, Quicksales.com, OZtion.com, ALLBIDS.com, BidMate.com, or Ebay.
You can also go to invaluable.com or liveauctioneers.com and search their directory for an auction house near you and consign to them.
