Brian, Post this to Richard Frajola's chat board. He has a pretty good knowledge on the Japanese chops and there could be others who post there--some very knowledgeable guys on that site, who can give you some info. He sent me an e-mail with some samples of Japanese chop cancels. I don't still have the-email or I'd send it to you. Mention it in an e-mail to him, and perhaps he'll send it to you. It's not a great source, but its helpful. I've, I think, two 3-cent and two ten-cents 1869's with what may be Yokohama "cross" chop cancels. I believe he told me he was not aware of any published reference on Japanese chop cancels, but that seems unlikely? I'd appreciate any link to other reference sources you may have on this. Occasionally I see what could be chops showing up on E-Bay, mostly on the tens, some stated as such and some not. Pretty high asking prices on those stated as chop cancels. I keep looking for a six-cent with a chop. The one you've posted looks good to me, but its not exactly a match on what's on the stuff Richard sent me.
