I love the antiques roadshow ,but this crap should not be having peoples money thrown at it the quicker the fee is abolished the better, people can subscribe if they want to sit watching this dross ...

I have quite a few books on coins and they all have sections on cleaning coins and what to avoid.
Was reading one yesterday and it told a story of someone who inherited his fathers silver coin collection.
He decided to give them a good scrub and brighten them up with silver polish.
Were worth 7-8 grand now worthless.
I don't think this can be true. If a tarnished silver coin collection is worth £8k, it's still going to be worth £8k when cleaned imo, and certainly not worthless. Most of these collections sell for the scrap value of the metal anyway, and the rare ones that are worth more wouldn't be reduced to nothing just because some old bint got the brasso out. What did she polish them with, wire wool?
