I would like to know what mint this came from (notice the crown symbol under the buffalo) and maybe what year it was minted and anything else someone might know about it. Thanks for your help.
Welcome to CT @steve60. This is bullion and not a coin, so no official US mint. Comes in gold also. And thanks for posting your photo in Full Image.
I found many exact examples of this looking around on Google and even eBay. Exact except that I could not find the same mint mark on any of them. In fact, it seems to be more common for them to not have a mint mark than to have one. It is known as a "Buffalo nickel silver commemorative" and was likely made around 2013. The lack of being able to find a matching mint mark and being able to identify the company that produced it gives me pause. It wouldn't be unheard of for the commemorative itself to be filled with tungsten or some such metal in its core. The Chinese, in particular, have been known to do this with bullion rounds.
FYI - tungsten is used as the core of gold plated fakes because it has an equivalent specific gravity to gold. It is almost double the specific gravity of silver, so if it was used as a core of a fake silver bullion piece, it would either be heavier than 1 troy ounce or smaller/thinner than a normal bullion round. Gold has a high S.G. Tungsten is one of the few metals that can match it, so that's why it's used in fake gold pieces.
Your round was minted by Monarch Precious Metals in Oregon. They're mark is a crown (Monarch...get it?). They are a fairly new outfit, established in 2008. Their website gives the specs as: Purity: .999+ Diameter: 39mm Thickness: 2.4mm Silver Content: 1 Troy OZ The only review on the product page is from October 13, 2016. So, they had been minted in 2016 or prior. I am sure if you email the mint, they would be able to provide any information you may desire. www.monarchpreciousmetals.com I have never dealt with this organization before, nor purchased any of their products, so I cannot give any personal experience about them.
NPCoin is correct. Thread is here on a different coin forum, but it's pretty detailed. https://www.coincommunity.com/forum/topic.asp?TOPIC_ID=351823 This has all the differences to identify the buffalo bullion coins/ "rounds" and where they were made, although it's a little dated at this time and there may be new ones not listed on that thread. Good luck!
