Cleaning (inexpensive) coins
I bought an inexpensive set of 1953 Elizabeth coronation BU uncirculated coins from the U.K. I paid about $12 and got a sealed but very tarnished set. The designs are unique and historical, but tough to appreciate since they are so tarnished and fairly corroded.
What is the best way to clean them and appreciate their designs. I wouldn’t do this to a rare and valuable coin, but this set was more about historical curiosity than collectibility
