2016 1.5oz silver QEII coin

2016 falcon queen Elizabeth II 1.5oz silver coin. 9999 It is tarnished as shown in pictures posted. Id personally like to leave the cleaning and polishing for the buyer as i am not a coin collector and fear causing a drop in value by something as simple as wrong chemical attempts. Not selling for silver value scrap. With our unfortunate death recently this is now a high priced collector coin. Please only serious buyers and will accept any reasonable offer. I am pricing from similar posts I have researched. As I said, not a coin collector so my knowledge to this is limited. However I am not dummy so please don’t disrespect me.
