Has anyone heard of any coin where one side is offcentre by 45 degrees? As in holding at top and bottom, then when one side is upright then flipping it around by the side, then the other side is not vertical. I know if both are vertical that is medal alignment, or the other side is inverted that is coin alignment.
The link above is for a Bulgaria 10 Stotinki ( Medal alignment ↑↑ ) which shows mintage for 1999 as 8,231,400 or 2000 as 10,000 Proof - but no mention of a known error for 1999 being mis-aligned.
Not that I know much about how coins are made, but is there not some way that alignment for both sides is fixed, so that the dies cannot slip? I have seen forgeries of UK £1 that are off.
Here are two photographs in front of a mirror - the one on the left is the 'error' one, and luckily I have a 'normal' one to compare with (on the right). Thanks :)
