Hi, below you find an old Austrian stamp from around 1904: an Emperor Franz Joseph, pink carmine, 1 krone. Normally the perforation is 13 x 12,5. However, this one has 12,75 x 12,5. I measured it a couple of times with a Lighthouse perforation gauge, but it is definitely 12,75 and not 13. Is this of any relevance or consequences for its value?
