Can't help you, but you should check in at your local museum or university for some info. I like history. I belong to a Civil War round table and collect many items from that period, although 95% of them are modern issues. I have a few Confederate flags, a new Confederate knife showing Robert E Lee with a confederate flag on the knife. This is history, NOT some political correctness that had most of the Confederate flags AND statues removed from many areas in the south.
As for the swastika? I metal detect and found a copper good luck piece with a heart, 4 leaf clover, horseshoe, AND a swastika on it. I researched it and found out the token was made in 1920.......BEFORE Hitler took that design for his symbol. But, I look at the swastika as being history, not anything else. I've been collecting coins for a long, long time. Some years ago, I figured the political correct groups would soon try to ban the sale of the 3rd Reich German mark coins.....WITH Swastikas on them. (It's O K for them to be sold in some European countries, but a picture can not be shown of those swastika coins.....more political correctness). I have an extensive German swastika coin collection now, and I think that due to P C, they have doubled in value in the last 6 years.
