An interesting excerpt regarding the 1882 no H penny:
When studying the Victorian bronze series it is essential to work rigidly to the principle that no new variety is acceptable unless it is entirely beyond question. Details in the designs of this series cannot be satisfactorily studied from worn coins, though, unfortunately, this is attempted by some collectors. The fact that only two really fine, undoubted examples of this penny have turned up during the nine years since this catalogue was first published is ample evidence of the scarcity of these pieces. Any worn pieces, seemingly without H, can now be re-examined in a much more favourable light. Craig tells us (The Mint, p. 335) that 'the Mint stopped work on 1 February 1882 for ten months'—for reconstruction. During this period the coining of bronze was undertaken by Heaton and it is extremely unlikely that the Mint would be in a position to strike any bronze during the January preceding this upheaval. This leaves December as the period during which these pennies without H were almost certainly struck —doubtless a small issue to tide over
