A number is a single term so there cannot be a 50th term for a number.
The 50th anniversary edition pistols really haven't attained that much value, given that they aren't particularly uncommon. A basic, blued Mk II with the standard profile barrel can be found new in the box in the $200 - $300 price range, and the value would be substantially less for a pistol which has been fired. You probably won't see much of an increase in value of the 50th anniversary pistols at least until Ruger marks its 100th anniversary.
