I see nothing in your photo that matches up to the photos and descriptions for 1974-D FS101 on Varity Vista. In fact there is no mention of a doubled earlobe or photos of such shown at VV. Can you provide any other site that references this feature? Or perhaps, just as a guess, the person who helped you on the site you failed to name is mistaken.
When you ask a question on an open forum you should expect to get some answers that may not align with your ideas or goals. There are a few roll searchers that pop into this forum from time to time, but they are not the core of members here. So it is not all that surprising that many here see roll/bag searching as less than a top priority.
While I'm glad that you had fun and I hope for you that you get some nice grades, the coin you posted doesn't look (imo) to be a worthy candidate for grading/slabbing from your supplied photos. Also in case you were not aware, NGC will not attribute your (assuming that you even really do have examples of this DDO) 1974-D FS101, it currently is not on the NGC list of varieties that they will attribute, which means that NGC feels it is too minor. It is likely that ANACS might, and perhaps PCGS if this is listed in the current cherry pickers guide.
