New Amsterdam Silver Co Silver Plated tea/coffee pot, sugar bowl, creamer set

Vintage New Amsterdam Silver Co quadruple silver plate 627 tea/coffee pot, lidded sugar bowl, and creamer set. I was gifted this set so can't really say much about the condition or history. I assume that for its age that it has normal scratches and wear from use. This is an "as is" type of sale since I'm not knowledgeable at all about silver plating and tea/coffee sets. I tried to take photos from all angles but if you'd like additional photos, please let me know. Tarnished and needs polishing. Also has some numbers that seem to be scratched into the bottom of each piece, off to the side. It looks kinda like "2367" to me but I'm not sure. The height of the pot when it is sitting on the table is about 7.5" to the top of the lid. This measure does not including the decorative piece at the top but does include the height the feet at the bottom add. The small decorative portion on top seems to be about 1.25" tall. The diameter across the top of the pot (with lid open) is approximately 4.25".
