6¼ amps? was this on a piece of equiptment?
I've come across odd fuse sizes before, but nothing fractional!

It seems like a odd number, but 6¼A∙120V = 750VA, which is sort of a ‘round’ number. It may have evolved with some UL appliance standard, and not the NEC we’re so familiar with.
I have some of those 6 1/4 amp fuses, but with edison bases.
I have a 1 6/10 Amp Edison-based plug fuse in my small (but growing - donations accepted gladly
) fuse collection.
The brand is K-E Thermofuse and is a porcelain plug with a brass/gold colored metal collar that holds the mica window in place.
