Bigcypresshunter,
Thank you for your response once again, and please do not apologize for being blunt. I joined these forums to get advice and feedback that I could not find elsewhere and I appreciate your help. If the coin I bought is a replica I am happy to accept that fact.
One piece of information that I should disclose is that since my first post on this forum I have purchased an additional 420+ silver coins from this particular source.
Before you tell me I am CRAZY most of the coins are dated 1800-1910 and are minted silver reales, pesos, or the like from Central America (Guatemala, El Salvador, Honduras...mostly) and are all easily identifiable to anyone who has a coin reference book at hand. Each one appears different and I have no reason to think that these would be replicas (although I am open to opinion).
I did purchase about 20 "silver cobs" with this lot of coins that are close to the condition of the coin that I posted photos of. These cobs are 1-8 reales coins, and supposedly they are all discovered from sites "in soil" or "in fresh water". They all appear to be different shapes, sizes, dates, etc. Considering the source I purchased these from I find it hard to believe that this particular person has/had the means to counterfeit this number of coins in actual silver and make each one appear different (this person is not even able to afford a car and is 3 hours drive from the nearest town). Although I am not stupid and I understand that he may have purchased them from someone else; but once again if you saw the town he lived in you would question where/how to get something like this

That is why I am interested to hear more from you on the topic of "one-of-a-kind replicas" and if you have seen this coin appear in your database before.
If you wouldn't mind sharing your email address with me I will send you additional photos of the cob coins I bought from him and you can compare them to those in your database/experience and let me know your opinion.
I am in PA, USA for a wedding this weekend but will be home on Tuesday and can send you any additional photos of the coins as well as the exact weight on a scale and any other information that would be helpful. Also please let me know what do you mean by pics of the edges? Do you want them straight on from the side or at a downward angle? Let me know what you are looking for and and I'll send them.
If you think sending a photo/photos of the coin to Sedwicks would be helpful I would be more than happy to do so, and if you have any advice or experience on the process your input would be greatly appreciated.
Thanks again,
Nick
