There are two top tier grading companies that are widely accepted in the precious metals industry as being the two leading grading companies; Numismatic Guaranty Corporation (NGC) and Professional Coin Grading Services (PCGS). We would recommend members to choose coins graded by these companies. Coins graded by these companies generally trade to a premium over coins graded by other less popular grading companies.
That's my issue, hence why i have date runs for Britannia's, Maples, ASE's, Kookaburra's, Krugerrand, Libertad's, Walking Liberty Halves, Barber Halves and currently working on Kangaroo's.
I like having one of each year and i won't be selling out for another 20 odd years, so i doubt prices will be less than what i paid, unless silver crashes to within an inch of its life.
