While many will say not to clean coins (I think it's good advise), consider 2 factors in this case; 1) Coin had no numismatic value as it was crusty, and 2) It's your coin, do with it as you please.
I found your video very therapeutic & the coin certainly looked much better. From what I've learned watching videos for 4 years, about coins, you just ruined the coins value by cleaning it.
Thank you for your expert and professional opinion, I completely agree with your opinion. Keep in mind that most of the time we lose valuable things to gain things that are fun for us.
