Maybe a bath and a closer image might help. But it does look interesting.

I use mineral oil and an old very soft toothbrush. (Your mother-in-laws will probably do.) Put some mineral oil on the bristles and brush in several directions then rotate the coin. But before trying this, experiment on a couple of dirty circulated coins to get the technique down first. Use only on circulated coins not BU ones This will only remove the dirt/grit, so be careful of sand as it could scratch the coin. After brushing (No Floss needed) place in a facial tissue and press to absorb the extra oil from the coin. Check with a scope to see if the devices are clean. If not, brush again and if you have some large gunk on it, you may try a green thorn so as not to scratch the fields. Again do not try this on BU coins OR Proof coins! Well unless you really want to ruin them!

Don't forget the practice method on a crap circulated coin to get the procedure down before trying this on a valuable one. I don't want to see you at my door protesting my bathing ideas.

The 1970S is a large date worth about one cent. Don't bother cleaning it off. Sorry.

Just to jump in, this might help when you come across another 1970 and you might not know what to look for in distinquishing a small date from a large date. You can tell the small date from the large date on the 1970 business strikes by the relationship of the 7 to the other numbers in the date. On your coin, you will notice the top of the 7 is not equally parallel to the top of the 9 and the 0, but sits slightly below the tops of those numbers. This is a large date. The small date will show the 7 equal on top to those other numbers. After seeing these over and over it becomes very obvious when you see one.

I really liked the pics of the coins cleaned with mineral oil. I have used about every stubstance you can imagine to clean copper coins over the years (always experimenting with garbage coins) but haven't tried mineral oil yet. I'm going to try it out. Thanks for sharing.
