Hi,
today I wanted to talk about the usable source list and their links. Over time, I eventually clicked on every link and found out a few problems. Note there most definitely are more problems, but these are just the ones I still know. First of the easy ones, which means links that are just not working, which are the following (you can try the link on the list linked above):
A. Tkalec AG
Central Bank of Cyprus
Ciscoins.net
Coins of Singapore
Copper Bullion & Coins
Numisa
Triskeles Auctions
And then we come to the more funny things .... links that are repurposed now. There we have:
Walder Coins (which now links to a french life-insurance information website)
World Bimetallic Coin News (which now links to a website of a crypto broker registered in the Seychelles from an Asian businessman)
And my personal favorite:
Union Latine (which now seems to be a website full of flashing ads, spam, scam and porn)
I would suggest to look into these "sources" a bit more closely.
