I'd love to post a picture, but not being able to include standard attachments on this forum has me at a loss. I've looked closely, it is definitely and clearly a 4, not a 9. It's bizarre. I have no idea what it could mean. I need help!

Hi all, I'm quite confused about my necklace. Says "Los Castillo Taxco" "Sterling Made in Mexico" "480".

Does the 480 refer to the silver strength? Or does it indicate something else? I've never heard of 480 sterling.

Any help would be much appreciated!
