B10 45 and 50sen repros and manipulations ...

 from japan, I have seen 2 imperf b10 repros of the 45sen and 50sen kobans ... both bear mihon markings ... also an unused 1yen has appeared with inverted crest on white paper ... a warning was posted in JP-isjp.org some years ago, mentioned that kobans exist with altered perfs, and fake mihon ovpts ... (never issued by IJP. regretably, there was no followup, identifying which kobans were on the list ... a tokyo group was the source. caveat emptor : beyond the imitation series, some skilful alterations of genuine issues or "gizu" exist ... follow the latest JSCA tables closely, and seek expertizatiron when required ... hopefully, the JPS expert committee will offer new advice to collectors.

incorrect design : flowers , romaji ...  does not match any known forgers




  • die size incorrect dimensionally
