I know it's impossible to tell if this jar has fresh gold from a picture, so you have to consider the source. The description of "THE GOLD TRIM IS IN EXCELLENT CONDITION WITH ONLY MINOR WEAR OR LOSS OF SHINE". Loss of shine? Original gold trim doesn't suffer from loss of shine. Maybe the refiring temperature does.
The description indicates, "Age - Vintage". For this to be true the gold trim has to be vintage too. This was an original/vintage jar before the alteration. This is the seller's history, not a rumor.
The reason I'm so down on this trickery is not only does the first buyer get burned, when they resell it the next buyer gets burned. When enough of this junk (there is quite a bit of it now) gets into circulation your gold trimmed collection won't be worth much.
