Kobans and the JPS ...
Japanese philately has changed more in the last decade than decades previous ...
The internet and new philatelic tools - the ability to scan and relay images to other philatelists; has assisted both research and the auction business greatly. JPS members are very active in this area, and many revisions to the specialised JSCA catalog reflect this today. ...
the specialised series in now in 4 parts ... classifications have been augmented, restructured and many new varieties have been detailed.... any serious koban collector follows this system. Old Koban group : 80 or 100 position plates , whereas the Yu and New Koban group were 100 or 400 position plates .... some die anomolies are detailed in the JSCA catalog - allowing separations of 100-400 plates ... perf variations : comb to bickel perforator.
narumi monographs ... ideally the JPS should offer the nissen catalog as download... by group : dragon, cherry blossom, koban, kiku, etc ... in pdf format this would be translatable for foreigners.
the JPS also has no foreign members ... unlike the ISJP.
Koban Forgeries and the ISJP...
Relative to the dragon and cherry blossom issues 1871-75, which have been heavily forged or imitated - identifying koban forgeries is an easier task. For novice koban collectors, MAEDA Kihei predominates in Japan. coverage is primarily the Old Kobans 1876-80. caveat emptor for 6sen, 12sen, 30sen and 45sen denominations however... some very skillful "unsigned" forgeries exist - sanko or "signed" forgeries are online @ the isjp.org ...
Again, the monograph on Japanese Classic Forgeries 2002 edition is a key reference for all... allowing an audit of personal holdings; and advice regarding acquisitions of new material from auction or dealers. Many houses today still post obvious forgeries as genuine stamps. ... ISJP.ORG site is superb ! you will find links to additions and corrections pages edited recently .... note also ... the isjp.org is offering a free service to members ... forgery objects will be reviewed via image scans provided via email transfer ... and a opinion rendered : forgery or not ..
