Question about Atocha 8 Reale coin TSI #

I recently acquired an 8 Reale coin from the Atocha. I have the TSI # but no COA. Is there a database where I can reference the # to make sure it matches my coin? I actually purchased it as a pendant but I intend on freeing it. I would also like your opinions on its authenticity. Based on my limited knowledge it is from the Mexican mint and appears to be from the correct time frame as other examples from the Atocha I have seen but I defer to the experts for confirmation.  I can't figure out how to compress my pictures yet or I would post some images. I will work on adding them tonight. Thanks in advance for any info you can share.

First, Welcome to Treasure Net !!
Two, perhaps very obvious suggestions: (1) Ask the seller if he has the COA; and (2) Contart the Mel Fisher organization about getting another COA based on the information you do have.

Thanks for the welcome! I am a long time lurker but this is my first post. The seller didn't have the COA. I was trying to find something easy that I could look up on line before I went the phone call route. All their COA records look very analog to me so that may be my only option.

More than likely, the Fisher organization has an online Email CONTACT address.

Rooter: this page has all the information and contact email that you need regarding your coin:

Thanks Tom!
The problem is I don't have a hard copy TSI # document so I'm not sure if they can help me. I have emailed them to see what my options are if any. The COA would be nice but I'm not hung up on it. I just want to see if they can tell me if the coin I have matches the basic description connected to that TSI # like weight, grade, mint etc...  just to authenticate it. I will post pictures as soon as I can figure it out.

turning actual coins into jewlery really angers me......

Welcome it to the free world! 

Agree with Alpha - should be a crime
Historical items should be left and conserved in their original state and not converted for commercial defile
