Your going to get all kinds of opinions on grading and slabbing !!!
IMHO Grading and slabbing is a waste of money unless you are going for a registry set!
The preference will be yours !! there are other methods of preserving coins,Intercept shields, airtites, and holders of this caliber work pretty good for preservation.
What it comes down to is how do YOU want to do it?
Pick yourself up a loupe 5x to 10x or both if you can afford it ,to help in seeing some of those tiny MM as well as a close examination for
VAM's and varieties of the other coins.
