If you can provide scans, and email them to the webmaster, he may be able to tell what they are.--Jeroen.

Everybody is welcome to add contributions here that have some meaning for others. I am quite liberal in letting things stand. However, if the contributions degrade to insulting remarks on other people's hobbies or worse, I will delete them.

Safety is a difficult issue, where anecdotical evidence is a bad guide. People tend to remember the one bad day, not the thousand that were uneventful. It is easy to blow things out of proportions. My purpose with the safety guidelines is to advise some reasonable measures to keep out of harms way, without spreading unnecessary fear.--Jeroen

That serial numbers are different seems natural to me: I would be much more surprized if they are the same. During the Japanese occupation, many provinces and even more towns printed emergency currency, often operating in difficult situations, and with very scarce resources: often using wrapping paper and lead from old batteries as printing plates. I know one person who has the a nearly complete collection of these (not me), and it is quite curious to go through them. I wouldn't also be surprized if after the war, a lot of fakes have been produced. If you have any notes, you can scan them and email them to me, and I can comment on them.--Jeroen.
