It would take someone with more luggage to accurately judge on that inscription but, within my limitations, i dare say it is just gibberish. Also the symbol on the left, a very early one, was certainly hijacked.
As (i think) i recall reading, in this case in Toledo, one of the crafts was blade guilding. This being a luxury asset, not always customers requested it. Also this being a very thin gold layer, tends to vanish within time.
