30-30 Diamond Jubilee Commemorative Edition?

Our guide on this hog hunt and I were talking and he informed me that the first deer that he had taken when he was a kid was a with Marlin 30-30 Diamond Jubilee Commemorative Edition. He was wanting to know more information about his rifle. From his descriptions it is in very good condition. Onthe side of the stock there is a blue and white commemorative plate that has Diamond Jubilee Commemorative Edition insignia. Anyone have any comments or know of this model, such as value etc. Oh and by the way he informed me that this rifle is still in family arms, and will be.... lol

Thanks, Dave
