Wow, dont think i've seen coins that badly marked.
i've always been put off ordering from them due to having to pay in Euros and having to pay the courier separately, although i'm sure most orders probably dont have issues but its just pain when it happens to you.
I've spent over £25k with silver-to-go.com/Coininvest.com over the past 3 years, you pay in £'s (inc delivery) into their uk bank account, usually delivered within 2-3 days, prices are as good too.
I've never had any issues with coins.. I had one heavy box that had a split in it which i rejected (as they tell you to) it went back to Germany, was opened checked, repacked and was redelivered within a week.
I hope they sort this out for you.
