2017 5p high and low relief coins

[ilikesorbe]

Something I’ve noticed is that the vast majority of 5p coins from 2017 seemingly have a much higher relief than other coins from the same queen portrait, but i have seemingly found a 2017 coin with much less relief than the other coins from 2017, much like the other coins from the same time period. I have a photo of the coins here

Better relief due to a plundered year specimen set?

Is the strike of better quality or is that die a proof die recycled for the next stage down in quality?

Does the bottom one look like it is from a worn die on its last legs?

Is the relief similar on both sides? etc.

All valid questions required to make decision. I won't say taken from a proof set because the rims aren't right, but that doesn't preclude the use use of a worn proof die or collar without the other bit. With less than 30K specimen and 14246 proofs struck across 3 sets, the dies should have plenty of life left in them.

the higher relief is not a one off, in fact the low, more regular looking strike is rare.

the relief is the same on the reverse between he 2 types

the die looks fine to me

I am not very well versed in proof strikes, but the features look very well defined on the more common 2017 coins, can’t rule out that possibility.
