Something odd about these two 1902H Canada 5 cents

Bought these raw 1902H 5 cents as part of a large lot of mostly certified coins. I noticed the odd looking raised areas on the 1902 large H and 1902 small H silver 5 cent pieces while reviewing the lot and it's been bugging me all day. I find it odd (suspicious even?) that the pattern on both coins is nearly identical. It looks to me like more than just a lustre break, the areas in question appear to be raised on the reverse and sunken in on the obverse. On the reverse look between the C in Cents and C in Canada, as well as from the leaf near the two up to the leave near the S in Cents. On the reverse, behind the king's hear and in front of his face.
It reminds me of coins that have been struck through grease, but the pattern is consistent across these two separate coins (of different type/size of mint marks) so I'd rule that out. The coins themselves are weakly struck, but appear AU58/mintstate with nearly complete lustre.
Is this some sort of planchet defect? I'm not ruling out the possibility of counterfeits either. Thought would be much appreciated!
Edit to add: the weights on both pieces are pretty much dead on (1.15g on my scale, 1.16g according to Charlton).

1902 no H from the same lot for comparison sake:

I too am interested in the reasons for this conclusion.
There may also be some die clash marks or ghosting in the mix too.

Well, just Love coins, period.
Here's the regular photos of each. The first pics were just to emphasize the strange areas I am seeing.

With all due respect, I do not agree. Note the strong metal flow lines. I suggest that these are genuine coins struck from well worn dies.

Agreed, along with high die pressure. Relatively common phenomena on thin coins especially British halfpence of the same era.

The only other coin that I have which has metal flow lines that resemble these are some ancient Roman silver coins.

I'll admit I was a little concerned over the extreme lack of detail on otherwise lustrous coins. Knowing that this is the look of worn dies is comforting
I am approaching 1000 posts here and threads like these remind me that I should definitely do some sort of give away soon. I'm thinking a mixed lot of circulated Canadian silver 5 cents that I've been sitting on for quite some time while not knowing what to do with them. I'll sort through them one of these days and will probably end up with some multiple lots. Any ideas for how to choose the winners in my upcoming give away post would be great
I find them interesting. Althoughh i had 2 of them another forum, the question of how and why was never really answered.

It looks like the phenomenon is in the exact same spots/shapes as on my coins. It also appears to disappear as the lustre is worn off the coin. In hand on mine it sure seems to bubble out/inward. But maybe it mostly has to do with the lustre rather than an actual, physical mutation on the coin.
