Nice catch and welcome!
You can learn a lot about these by reading the posts in the Navy sub-forum; Navies are popular and can get a little complicated as to variations and markings. Many have been faked, yours looks good as already said- you got lucky; I believe there are as many "messed with" Navies as legit ones on the market.
Value covers a broad range- it is easier to say you got a good deal or not if you want to share the price.
We're scattered around the country, I did not see your state or city in your profile- perhaps you are close to one of us? And a first name would be nice, I don't want to call you a "monkey".
