That is what is so tough about these lots, our minds want to see certain things when we find no date D and S mint coins. I can see the elements of a 7 there, and it looks to be in the correct place. Have you lined it up with another 17 type 2? I often do that when trying to decipher a weak almost non-existent date on a coin, just to be sure the size, font, and locations are right. I sort of hold a legible one over the top of the unknown or vice versa, comparing via magnification to get the best read possible.
More photos would help here, especially a photo of a known '17 type 2 along with this one. The rest of the coin is in very good shape....congrats.
