Yes, I'm wondering why a silver-colored buckle would even say Solid Brass. The early 1997 handbags were still using brass hardware so the buckle probably shouldn't be silver anyway.
And I'm wondering about that color. I know colors hardly ever look the same to a camera or monitor as they do to the human eye, but that color looks like a Jade Green but the greens for the 1997 Sohos were more Leaf or pale Lime colors. In fact Aqua, Lime and Leaf were the names of the 1997 green colors according to
Coach's catalogs. I don't remember anything even close to the color in the listing being used by Coach, but there may be colors made for special stores or retailers that I've never seen.
I can't say for sure either way, but it's probably safer not to buy it.
