So I never do this because I never sell anything, but this is for my Mom. I am at a loss as to where to look for the references of finding this DDO a Swiss 5 FR, here is my thread in error coins https://www.cointalk.com/threads/1969-b-swiss-5-fr-ddo.254735/ I have sent a few emails to have the coin attributed, but I have no replies as of yet. I have searched some eBay for this DDO no luck. I have tried online, no luck. I got into NCG and right before I got to see anything they kicked me off as I am not a member. So I am really asking all you guys for some help to let me know if this beauty is a rare and a valuable one. If you guys might know who the best is to go to for a Foreign coin to have it Attributed, conserved and slabbed. Thanks all!!!!! Oh and when I looked this up before one site said it is not silver and today a different one said it was. I guess I could try the tissue method, I wonder if toilet paper will work doh
www.schweizer-geld.ch/home/en/0 So, I found this site that list the errors for the Swiss 5 Franc, no DDO's or DDR's. I sent the site creator an email and he said he has not seen an error such as this for this coin and he himself will now be looking for it, LOL. The variety errors for it are Die breaks filled in 9 and a 2, reeding, clip, rotated die for various dates of the 5 Franc and some of these are valued pretty high. Other sites stated that for this coin the Swiss have a low rating for errors (high percentage of no errors). Funny though, since he did not ask to have it or make an offer he must not have thought it to be rare or he didn't think to ask. Or like you said no interest in that market.
