Swiss 1921-B 1 Fr Double Die Bb Mint Error Coin

I'm certainly not an expert in world coin errors, but I would think that this error may be too small to demand a high premium. The error coins that I see selling for big money are the off-planchet, off-strike or multiple strike coins. I have several errors in my collection like die rotations, broadstrikes and defective planchets, but I don't consider these significant enough to increase their value by much.

I believe this is what is known as a "repunched mintmark". It would be classed as a die variety, rather than an error, because the mint intentionally made it look like that.

Die varieties generally don't attract too much of a premium, though in many cases they're not very well studied so no-one knows how "rare" they are. But it's not likely to be unique; thousands or maybe even millions of coins could have been made with this variety, depending on at what stage the repunching took place; I'm not familiar with the procedures and practices at the Bern mint.

It's a nice find for a specialist, I'm not sure how many Swiss RPM specialists there are out there, so that will likely keep the collector value somewhat depressed unless you can find a way to get everyone to look at their 1921 1 Franc pieces to get some idea of the population. I will check mine at least, and get back to you.

The B/B looks a lot like a strike double to me. However, I do know that there are NUMEROUS repunched and double punched dies in the Swiss series. They are most common in the lower denominations - especially the 5 Rappen (if you have a 1944 5R nearly every die was doubled so that a single image is scarcer than doubled or tripled) - but they occur in all denominations. I have perhaps 100 different examples at present (none at home and none photographed unfortunately).

The issue of value versus rarity is critical in this case. There are few die variety specialists for Swiss coins (because of genreal lack of interest in the whole series) so these have essentially no premium value. I do not know of any publications on the subject. There was a fellow on ebay who sold a lot of 19 examples (all doubled dies) and he got about $1 each.

I collect them because I like them. It is like the doubled dies in the Panama and Columbia coins. I get them out of junk boxes whenever possible and put them asside. They usually cost a few cents each and if anyone ever publishes on the subject - perhaps I will have a valuable one. In the meantime, I just have fun with them.

I think that is the best approach.

How can I find info from the Swiss mint and obtain information on there error coins if they would consider this as an error or not, what do I do to obtain this information from them, any ideas.
