1961 Roosevelt Silver Dime DDO Question.

I have a 1961 Roosevelt Silver Dime and to me it looks like it has a little doubling on the letters E & R in LIBERTY. I haven't came across any know doubling errors on this year,make & model dime so any clarification and suggestions would be greatly appreciated. It's my opinion that the coins over all appearance is still in great shape considering the fact that it has been in circulation but the wear & tear on the coin seems to be down to a minimum of maybe 2 to 3 years in circulation. It has no mint mark and its definitely made of silver material as for the metal content used. The full band's are visible on the reverse as well. Any opinions,clarifications,or suggestions on the doubling of the letters and if I should even invest the money to proceed sending it off to have it professionally graded. If it's not worth more than face value then it probably isn't worth the hassle. Thanks for any advice in advance because this coin community has definitely helped me out in the past.
