Please view our selection of certified coins for sale. Certified coins are coins which have been independently graded by a grading house (or grading service) and then encapsulated or 'slabbed' in a hard plastic holder. Quite simply some people prefer the security offered by independent grading and the protection that the encapsulation offers the coin, others prefer to buy the coin in raw form. We now offer a small selection of good quality certified coins, please let us know if you have any specific requirements.
