Brand new about $195.00. * They have been made since 1960 and I recently bought a used one for $60.00, in excellent condition. Depends on the letter/letters following the Model #... 99 99C 99DL 99E 99M1 etc..
That's hard to say since there are several different ones listed for the model 60 with at least three different lengths. They are all .22's, so you may be able to modify a longer one to fit your model 99. See Numrich arms: http://www.gunpartscorp.com/catalog/Products.aspx?catid=11759
Visit the Numrich Marlin/Glenfield page. Or the Marlin home page to download the PDF version of the Model 60 manual. These two rifles are very similar in design. http://www.gunpartscorp.com/catalog/Models.aspx?catid=310 Marlin downloads. http://www.marlinfirearms.com/customersupport/manuals.asp
Your Marlin model 99 which was a Promotional model and made only in 1959-1960 will bring between 75-150 dollars on today,s market.
The Marlin 99 was a low-priced utility rifle made only from 1959-1961 and it has not much collector value. Today they sell for under $100 and Micro groove is no longer used by Marlin because it wore out too quickly. It was used to lessen production time and cost.
In today's market in 90% condition you should expect to get around $95 to $115 Jan 2013
Google Numrich Arms. They have many parts.
I assume you are asking about the 99 "Champion" not the 99 "Target special". In good condition it would be worth between $45 - $60
Plug the phrase "Marlin Model 99M1" into Google, and you'll find a wealth of data and sites relating to this firearm.
