Check this out and tell me what you think it is

TB, I carefully searched the site you linked above, I couldn't find anything even remotely similar to this badge. They only sell novelty items, buttons, for like under $10, but this badge is huge in comparison, and it's sterling silver.

I found info on the web searches I did that indicated that there are a lot of fakes, replicas out there, so I'm trying to figure out if mine is real or not. If you were holding it in your hand, you can feel the weight of it, it's very well made, and solid sterling silver (I believe)

I usually do a fair amount of Google searching, like you suggested :) but that giant tooth sorta caught me off guard. I didn't do any searches until after it was posted that it was a shark tooth.

So, any opinions on this badge? Reproduction? Fake? Authentic? It certainly appears to have the genuine 'patina' of an antique badge.

I didn't want to post what I found because it was a PDF, and this site loads the entire document.
It is an Edward Jones order form, but it also says at the bottom of the page to make sure your badge number is correct.
Maybe they also make legit officer's badges?

It looks to me like they sell a few different items that include charmes and such, but at least your badge is one of the more expensive items. :D

I tried to link it in this post but it wouldn't load.
Try a Google search for this exactly and you should find the PDF order form about 3-4 results down the list.
