My grandfather played trumpet from the age of 13 in New York city until a few years before he passed away this past thanksgiving. About a year or so before he passed away, he gave me his trumpet (I play also) and now that he has passed, I am trying to find out some information about it to see if I should have it insured, if it is valuable enough to need insurance. I have no intentions of selling it because it is worth much more to me than money.

It is a Holton Stratodyne Serial #356810

Thank you for your help!
