I have also noticed a lot more PR70's being slabbed lately, especially in the statehood and parks quarters programs. Maybe the quality of the dies are much better, perhaps they have improved on the presses. Hard to tell, or simply put it is the grading companies relaxing the rules.
Take that 70 grade you have and compare it to the same coin graded a 69, you should be able to see the difference without any magnification. Look at the fields carefully, are there any signs of waves or imperfections in the fields.
I have both an MS69 and MS70 Eagle, as well as 2 Proofs Sacagawea's, both coins are from the same year and mint, place them side by side and you can see the difference.
This is great education for coin clubs. Cover the top of the slab with tape and have the members pick which one is the 70. After a few times one can spot the difference quickly.
But if you look at some of those PR70's of today, I don't see the same quality as the older coins graded at a PR70.
