These are 1 oz silver Buffalo rounds. It is one of the cheapest and close to spot price silver rounds available. Not too fancy looking like the pirate ones but more bang for your buck. It is the same design as the popular Buffalo gold coin from US mint

The market is down again in cryptos and precious metals also very low. I will just buy every now and then when i have spare money as savings.
