Hi Barnzy.
If you have a show nearby i would go and have a look as soon as you get the opportunity.
The dealer will be able to answer the questions you may wish to ask.
Lots of coins of different years and denominations to view and have a look at (in hand) of which the grades will be alot more on the mark than the pictures and descriptions on ebay.
Also type in the search button top right on this forum , anything you may be interested in has probably been discussed before.
Welcome to the forum and happy collecting
Pete.
