I'm delighted that you are happy with the badge and I hope you can sell it to someone who will value owning it.
I tried to sell it on eBay but they won't accept Nazi items. I then contacted several dealers via a Google search who mostly offered me £40-£50 after some haggling. Most of the other dealers tried to conceal its true value in their replies and also lacked manners which doesn't inspire confidence.
Ultimately it's about trust. I should think that most prospective sellers have done their own research and therefore know roughly what their item is worth. You were the only dealer who had the integrity to concede that my valuation was approximately correct and I respect your comment that you can't offer this as you need to make a profit. Your honest approach is greatly appreciated and I felt comfortable taking the risk in sending it to you.
