Is this navy button from the civil war?

[Ripcon]

Here's a button I found at a plantation site on the Mississippi river that served as an area where union boats delivered men and supplies during Grant's Vicksburg campaign. I don't want to just assume it's civil war period, but I'm hoping it is. Unfortunately, I only found the face of the button, the back is missing. Can anybody with knowledge of buttons give me confirmation of its age? I cleaned it up and put a little olive oil on it which gives it a little darker appearance. Thanks for any assistance.

I have looked at several button sites without finding a match to your button, so I will have to go on what little I know about them. All the military, both domestic and foreign, anchor buttons I have seen has the ring pointing up, not down as yours shows. The closest was a merchant marine that had the ring at an angle to the left side as you look at the button. The rope on yours goes over the stock to the left side, again as you are looking at the button. I don't remember seeing one military or career uniform button with the rope doing that. The back is missing but there appears to be some remnants of it under the lip and, as best as I can see they are corroded indicating that the back may have rusted away.
So, with all that said my humble opinion is that your button is a civilian fashion one from the mid 20th century. Hopefully, someone else will come along and prove me wrong and ID your button correctly.

One sites opinion on this button at bottom,
refuting the "Chief Petty Officer" claim made by some.

Here's a little more information on Chief Petty Officers:

Chief petty officer (CPO) is the seventh Enlisted rank (with the paygrade E-7) in the United States Navy[SUP][1][/SUP] and U.S. Coast Guard, just above petty officer first class and below senior chief petty officer. The term “rate” is used to identify enlisted “ranks” in the sea services vice the term “rank”. Chief Petty Officer is the rate. Gunners Mate is a rating. E7 is a pay grade. Only officers hold rank. The term rating is used to identify the career field of a Chief Petty Officer. For example the rate of Master-at-Arms in the rank of Chief Petty Officer would be spoken as Master-at-Arms, Chief Petty Officer or Master-at-Arms Chief. Additionally it would be officially written MAC (Person's name), USN/R. The grade of chief petty officer was established on 1 April 1893 for the United States Navy.[SUP][2][/SUP] The United States Congress first authorized the Coast Guard to use the promotion to chief petty officer on 18 May 1920.[SUP][3][/SUP] Chief petty officer is also the final cadet grade in the United States Naval Sea Cadet Corps.

The NSCC was founded in 1958 by the Navy League of the United States at the request of the Department of the Navy. In 1962, the USNSCC was chartered under Title 36 of the United States Code as a non-profit youth organization with an emphasis towards the sea-going services of the United States.[SUP][1][/SUP] The law was amended in 1974 to allow female participation in the USNSCC.

Although this is not always the best Authority on IDs, I do agree with it being 20th C, & most likely Merchant Navy, not Royal.
