Wondering if anyone can help identify a few items. I recently came in possession with many things from my mother. She had an Early American hand painted plate that always was of interest to me. It has the blacksmith from an early period with the backstamp of a cross and the letter TRE beneath it and the name espara or espana engraved next to it. I know it came from my great grandmother and am unable to identify the markings. Secondly, I went to an estate sale and bid on a Cobalt blue cut to glass bowl weighs about 8-10 pounds and 10 inches round. No markings at all but I believe it’s lead crystal and it pings when I hit the top of it. Very new at collecting and don’t know how to value or identify things. Have other interesting items as well. I can post a picture later if needed. Thanks in advance for any help I can get.
