1843 Penny UK with colon (REG:) condition?
Hello. I bought a small bulk lot of coins at an online auction recently. Amongst the coins was this 1843 UK penny with a colon after the word "REG" on the obverse side. I'm new to collecting coins so I am hoping some more experienced collectors could give me their opinion as to what condition this coin is in. I was also wondering if I should clean it or do something to remove the corrosion around the letters. Thank you.
