Can you tell us anything about the age of the sample, and where it is used? Are there any other letters that can help prove it is a font? These three letters are not much to use for ID purposes.

In looking for this I found a similar font that might be the answer: ITC Symbol Black Italic. At least it seemed close to my eyes. Your sample looks like a tiny serif style, and that was how I searched for it.

It must be ITC Goudy Sans Black (Italic) by Frederic W. Goudy [1929], published by ITC on 1986
The sample looks a bit expanded
