Currency. Too many things wrong for a proof. Using Peck's arguments for proof examples, the 1 should be clear of the sea, no flaws and should have a grained edge (which both currency and proofs have). The rims aren't good enough either. Peck also states the currency as having a grained edge in a deep groove, whilst saying the proof is merely grained. Normally this means light oblique graining in the centre of the edge, not in a groove. However, if it wasn't in a groove, there would be no reason to mention the other criteria as this alone would suffice. Muddy waters here.
Prooflike examples are frequently encountered, but that is normally an early strike using fresh dies. Not surprising if you think about it, as a resetting of the press will probably require the force to be adjusted to reflect the new positions of the dies, which despite being nearly there, are inevitably going to be a few microns out as a minimum. Think physical length and diameter together with the depth of the relief.
