Unless you are talking about 1974, I see no numbers, only a coin that has been in acid or coated with it. Or possibly, left in Coca-Cola for weeks. The surface would be the same

If it's dollars, it means short water line on the reverse.

XF-40

From the photo, yes, it looks like a fat 4. I'd say it's XF-40 and a nice coin.

I agree. It's machine or mechanical doubling (MD) and adds no value to the coin.

I'll guess AU 'details"

I agree with coinguy.

Not doubled. It's a tired worn die and it's called die deterioration doubling.

To me, it looks like die deterioration, but a beautiful coin.

It's not a "dot". It's in the wrong place and wrong size.

Since the "crack" is on top of all the design, it looks like a scratch, not a D/C. With all the other scratches and marks, as well as the wear on the hair ribbon and beaver joints, the coin is not MS. I'm not sure that it would even get an AU. Your coin is PMD, not a D/C.

Looks like it to me, but I'm not a penny guy.

Yep, a DP3, a DP 4, and a TP#1. And the DP5 earlier and one of the nice 5's. And another, we didn't put a name on, just the page number in 2011. Nice Mikey

Looks silver to me, not a cent?

Mike .... the Zoell R2b became the DP#5 not the one above, with the inside of the loop having the huge offset and showing well under the top. It also had the huge D/C at the R in Rina and then split to go into Gratis and the rest of Regina
