It depends on your definition of good condition. Does it need a neck reset? Most do. Are there cracks, or worse, repairs to the neck? Is the finish original? All these factors can swing the price by thousands. So, without photos and a detailed description, any answer would be a guess, and many people would throw big numbers out there just to make themselves feel knowledgable and to make you feel good. I'd say you are looking at $2500-$7000.

According to The Martin Guitar Site that serial number was used in 1967.

The 5210 is a student guitar. If in excellent condition, with no excessive neck bow, you might - I say might - be able to get $50 for it.
To get a true value, the model number is needed. There is a HUGE difference between a D-18 and D-28 due to the wood type. All pre-1969 Martin guitars with a model number of 21 and higher are made from the now SACRED BRAZILLIAN ROSEWOOD from deforesting the amazon. In 1969, there was an international ban from harvesting that old growth wood and Martin switched to the more common INDIAN ROSEWOOD. Hence, a rosewood Martin from 69 or earlier is worth ALOT more than the standard mohagany guitar. Condition is also a HUGE factor in determining the value. In describing the condition, it is common to use a percentage. 100% being mint and unplayed and 20% being unplayable. A clean uncracked but well played guitar would be in the 50 - 60% range. A 1947 D-18 in 60% condition is worth (on the street) about $4500-6000. a 1947 D-28 in 60% condition is worth about $12,000 - 14000.
$3000 if in good shape
One cannot give the value without a thorough evaluation of the guitar. I have a friend who has a Martin guitar from the period 1850-1870 (estimated at the Martin factory). Martin did not estimate its value, but an independent estimate put the value in the $5-7K range. To the right collector, this guitar might be worth much more.
I just picked one up the same condition for $1250.00 U.S.
