TX Tim .......I hate to disappoint you, but I'm 99% sure that this is a large date. I had several coins that looked exactly the same as yours. Key thing: You literally CANNOT tell by looking at the seven (7), despite what the articles and websites say. I spent hours going through all of mine that I thought for sure were small dates. I finally took everything I had to a coin dealer and sure enough, this was confirmed by THREE different people and immediately upon looking at them with no hesitation on their part (the coin dealer/store has been in business for 40 years). And they all said the same thing. Then they showed me the real thing for comparison. And it wasn't even close. I couldn't believe it myself. Anyway, take your coin to a reputable coin dealer who has them in hand in white slabs. I also believe that the small date has slightly faded/altered ER letters in liberty, which is another way to confirm. Also, I believe that most of the 70S small date coins were only available in the 1970 mint set (or a variation therof), which is why they are extremely difficult to find in the wild; the breaking up of the 1970 set is hugely beneficial, because there were THREE unique coin situations in the set (not just the unique 1970S small date).
When I looked at your images, I didn't even hesitate. Plus the 1 is not flat with the top of the 9...and the 9 needs to be more skinny. Finally, the zero is different on the small date.
Oh, by the way, this is also why the slot for the 1970S small date in my Dansco album is empty, as I refuse to pay $65.00 for it.
Someday, I will probably break down and purchase it for some silver halves that I found in a bank roll...this way, it's not so financially painful to me. Ex: 6 silver halves=$66.00 but I only paid .50*6=$3.00)
