Why should I grade my 2012 and 2013 Casascius coins and where?

[Narydu]

I still have several unopened Casascius Coins form 2012 and 2013 and never even thought about grading them. I even have the original emails for each purchase set and Mike’s wallet list included in each pack. They are in mint conditions.

So what for should I grade them? I been selling them in Argentina with no issue. But... Who does this grading? Can it be done in every country? How do they do so, meaning based on what?

Also, what are market prices today for 2012 and 2013 coins, being them brass?

I'm not sharing pictures as said, they are several and this is more a general question.

Honestly the reason to grade coins is for the slabs.

Most grading is done is the US. ICG is out in Florida, while the other less recommended grading company is ANACs in Colorado.

If you do grading, it would be wise to hand deliver the coins to whichever grading company you choose.

Also recommend pictures of the coins as if they are brass they would be worth lower than the silvers, or gilt silvers.
