This brooch is large (3" x 2") and weighs 51 grams. Features a cenral oval shaped porcelain plaque with what appears to be a "transfer" painted courting couple minuature signed "Boucher" in script at the bottom. Ornate gold plated open-metalwork frame with a silver colored base metal. I tested the base metal using acids and a touchstore, and the streak did not change when exposed to 14k and Platinum acids. However; I tested another vintage "pot metal" piece and obtained similar results, which is very strange...Anyways, the finding is a one-piece saftey pin that was applied to the backside. I cannot tell if it is original to the piece. This style of pin was patented in the 1940's, I believe. There are no hallmarks whatsoever on the metal, and the only identifiable marking is the Boucher script on the poreclain plaque. The painting appears to be reminiscent of Francios Boucher, which leads me to belive this piece was not created by Marcel Boucher, the well-known Vintage jewelry designer. This piece is in excellent condition - only a approx 1mm sized area on the side of the pin where the plating has worn away. I would appreciate some feedback on this piece, as I have been researching it for a long time and just cannot seem to identify the date of manufacure, material composotion or designer. I would like to list this piece for sale in my Ebay store (Nikki's Estate Jewelry Boutique), but I do not feel comfortable selling items that I am unable to authenticate, and I cannot seem to figure this mystery out on my own. Thanks so much!

I got this lock from my grandfather and i wanted to find out some more information. The lock has a three digit combination. There is a picture of a bicycle on the back. 

Purchased in a flea market in Tokyo 10 years ago, I have NO background at all for this item. I'm concerned as it is showing  signs of oxidation which I used to clean with orange oil that is no longer effective. I very much want to preserve it properly so part of this outreach is to determine the best way to clean it as well as trying to obtain a value. Based upon the value I may be inlcidned to sell it. 

Antique (I think) chess set of Asian origin. Was an inheritance and I'm trying to figure out whether the fact that I literally cannot find anything exactly like it anywhere is a sign of rarity or obscurity. I want to sell it, but I would like to have some idea of its true value before I embark on getting it sold.

Thanks

We inherited my husband's grandmother's house and this is one of the items that we have found.  It is in really good condition.  The paint is more vivid than the pictures make it seem.  There are superficial lines on the inside of the lid, but it doesn't have any real cracks or chips.

This was a gift i have no idea what it is can someone please help me
