Well, we'll miss you.

No you won’t. I do like your public transit system, though. One of the best airport links anywhere.

Just Bob, sorry for delay in responding. Fell asleep. Don't mind posting pics. 

From the looks of it if you did not scrub the coin it looks like someone before you has cleaned it.

Learning how to clean a coin is tough because of the reasons already posted. There is something more important and just as hard to learn. The process starts with being able to spot coins that can be helped and those that should not be messed with. Some coins can not be helped. This is where the services come in. They have the skills to decide if a coin can be conserved or not.

The answer to the cleaning question is always NO. NGC states that a thorough rinse under warm water with NO RUBBING is sufficient to remove surface dirt and contaminants (with the exception of PVC residue), and the coin will still grade numerically but anything more will usually result in details grade. Submitting your coins to NCS will solve other issues such as PVC contamination and will not affect the original surface of the coin, but that also is assuming it was not previously cleaned before you got it.

You learned a lesson the hard way. No more YouTube videos (unless you watch ANA or Mint videos, there is too much wrong information on Joe Blow's videos).

I’ve seen Joe’s last name spelled Blough. His videos are even worse.

ZACKLY! This is the first key - important to know but difficult to learn.
