I don't know, I always collect metallic-looking rocks, but none of them react to magnets.
Can you share photos?
I am going to Europe soon, do you think I have a better chance of taking them with me and selling them there?
What do you think? You can sell on Ebay and ship across Europe, instead for having a market of a 6 million poor people, you have a market of what, 400 million rich people?
Last time I sold some parts from France but I was only there for like 3 weeks. After I was back to Lebanon one of the parts was returned but there was nobody there to receive it so it was kept at the post office and they would not accept to release it without seeing my ID, which was impossible because I was in Lebanon.
The rules are particularly annoying in France, if it was another country it would probably be simpler.
In the end I bothered my friend and lost money.
So if you want to sell in Europe plan in advance for the possibility that the item will be returned, post in advance to win time, it is much easier if you are staying there for a month or more.
