Protective case 0

Just got my End of WWII silver.  Besides the grading, is it worth paying for the cheapest tier to get it mounted in a slab for long term collecting?  Will it prevent tarnishing?

The best protection is to leave the coin in its original US Mint plastic (if any). Exposure to dust and dirt in the air has greater potential for spotting and other problems than leaving it alone. None of the TPG holders are completely inert, filled with pure nitrogen (or argon), or hermetically sealed.

But - if you want to sell it for the most money, then buyers want in TPG plastic.
