The value of the coin depends on the grade of the coin. The certificate means nothing. In general the coins are valued from $1.00-$5.00 in average condition.
The "certificate of authenticity" wasn't from the Mint. It's really only worth the paper it's printed on because 1962 halves are quite common among collectors and the likelihood of counterfeiting is minuscule. However, the coin itself is worth something because of its silver content. Please see the Related Question.

With NO autograph, and in mint condition without a single flaw, that card is worth 50 cents. Autographed, it's worth about $10. If you tried to sell it on eBay with no certificate of authenticity, you'd be lucky to get half of that. Source: Huge memorabilia and card collector
It depends on what company issues the certificate of authenticity. If it is a Steiner Sports Marketing product it should be worth around $175 for an 8x10 or $250 for a 16x20. If you have a certificate issued by a company nobody has ever heard of the value plummets as the certificate isn't worth the paper it is printed on. No name company could be worth as little as $50.
It can be worth any were from $20 - $40 it would be a bit more expensive if you can get a certificate of authenticity for it and if it was actually used in battle.
Dates and mintmarks are needed, post new question.
