How do you authenticate antique coins?

Answer:

There are several firms that will certify coins, old or modern. Most coin dealers are members of ANA or PCGS and can submit coins for you. There are other, less widely recognized, firms that will accept coins directly from collectors. But be warned, there are some pretty high fees for these services, so most collectors will only submit high-dollar items that are more likely to be faked or altered.
