The thing with trial strikes is that they are a bit of an unknown.
If you look at the decimal patterns of the late 1850s, many of the flans laminated. The striking pressures will be different for the previous issue of copper pennies compared to that required for the thinner bronze equivalent. In the case of the 1/20th of a shilling pattern halfpenny, all known examples have this defect as does the unique F689 and probably other things struck on a flan of similar thickness.
What cannot be known or appreciated by the layman is the number of unpublished failures suffered before they got it right. Anything that failed to make adopted status will be frozen in time, so a cracked die remains just that.
It's been a while since I posted on here and meant to come on months ago!!! This I'm guessing was an auction lot for one of our sales last week? I don't do any of the grading or cataloguing for the auctions, consultants are used. I do the grading on the retail side, though any coins on the website which were there before I started were done by the old team.
