So I few days ago I said I would start sharing some of my coin collection so the first coins I'm sharing are super special and rare they are sir Isaac Newton fifty pence coins I had three sold one but kept two they are mint condition never been opened

Here is another picture from the back I love collecting all sorts of coins to me they are a good investment for the future but it's not just about that I like the look of coins like this I have so many two pound coins and one pound coins and fifty pence coins I paid £100 pound for one of these coins when they was first published and you could only get them from the royal mint experience in Wales
