Most companies charge more to have autographs personally inscribed. Are personally inscribed autographs worth more?
No, to the contrary, they are worth less than uninscribed autographs. Personally inscribed autographs are only more valuable to the person they are inscribed for and carry no additional inherent value to any future collector. To a true collector, uninscribed autographs are just a little more valuable than inscribed autographs. To use an analogy of another collectible, it is similar to the difference between a coin in mint condition and one in fine condition. Both have value, one more than the other. Most companies charge more because they pay the astronaut or aerospace celebrity more to personally inscribe autographs. Plus, they can make a little more.
