Qrt.S, thank you for the information. I really appreciate your research. dragonflywink, I didn't notice my spoons have upside down "H. I." I thought they are "TH." Well, it is still a mystery to me.
I have these two spoons, but I have no idea if they are coin silver, 800, or 830. Can anybody identify them? http://s20.postimg.org/4sc1dmn6h/imsland1.jpg http://s20.postimg.org/45d4o3qah/imsland2.jpg http://s20.postimg.org/y8rng1tjt/imsland_3.jpg
