"Is a letter worth it" is a question that only you can answer. If there is some personal significance to the gun... or a chance it was used by some recognized historical figure... or if you think it will increase the value of the gun... then it might be worth getting one. If not, then it's kind of a crap shoot. 
I'm not a letter kind of guy so take that into consideration.
