Hi MaryJF - Yes, it is doubling and commonly refered to as machine doubling. Unfortunatly, this type of doubling is classified as "after strike" and although a few do collect this type of "error", it is not worth any premium to the value of the coin and in some cases can cause a devaluation of the actual coin's worth.
Machine doubling can been recognized by the flat, shelf-like appearence of the doubling. It is caused by a loose die (in this case the obverse die). There are other types of doubling that also fit into this catagory; die deterioration doubling (best example of this is the poorman's 1955 doule die) and ejection impact doubling are just some of these that are in this group.
Just a suggestion; take a look at the doubled dies that are on site and it will give you a feel of what to look for in a true doubled die. The one BIG thing with a true doubled die is NOTCHING; this occurs at the serifs and/or terminii of effected letters and numerals. Once you get the idea of what to look for, spoting the difference between machine doubling and doubled dies becomes alot easier.
Hope that this helps MaryJF and as always, we are happy to help with all posts. That is what this great hobby is for.

If I may jump into this string while on the subject of Double Chin? Would the doubling at the chin of this cent be in the die deterioration catagory. Doesn't appear to be strike doubling. I've seen a few like this 1967 and was curious.

You are correct Steven. This is considered die deteriration. It will be found most often in the 50's and 60's, especially 56-58.
