OK, so I conducted the experiment, having regard to the actions in the video:- Step 1 - assembled the necessary items, and Step 2 - place the ice cube in the glass of water and place the string across it

Amp ly done

Only about 3 minutes - but then I was supercharged. You mean your post wasn't your work?

Got to get some ice cubes first. It'll be interesting.

I'll give it a go myself and let you know.

Challenging times, and being static must be frustrating. Still, a pity he has to re fuse jobs for the time being, and his current financial situation is obviously pretty grim. However, he needs to be patient before switching to something else. Eventually though, he might need to step up to transform his prospects. You never know, maybe one of those light bulb moments might elicit a really good idea - enable him to become a real livewire again. I'd never judge his actions though - always wholly neutral in these things.

I don't see how it can work anyway. Salt is used to melt ice, not promote it still further.

I presume that's said tongue in cheek, given the damage that bleach could cause a coin. As JLS says, the risk is negligible. In any case, all the buyer has to do on receipt, is open the package, inspect the coin, put it way, dispose of the packaging, and then wash their hands thoroughly.

There could be a few, obviously, but the market won't be flooded with them. Let's not forget stats here - even if say 5 million catch the virus, that's still only 7% of the population, and the vast majority of them will soon recover. More likely some collections/part collections will be sold because their owners are out of a job due to the extremely adverse economic situation created by the virus, and need money urgently.

That pre-supposes the ambient temperature is below freezing point. If it is, then at say -18 degrees, all the water in the glass will freeze within a few hours, and your piece of string will be trapped in it, together with the original ice cube. Or even at just 0 degrees, eventually the entirety of the water in the glass will freeze. Above freezing point, the water will remain as water, and the ice cube will melt at a rate commensurate with how far above freezing point the surrounding air is. It will be shrinking as it melts, and therefore not able to trap a piece of sting within it.

I don't think it will take a massive hit since most coins are now bought and sold over the internet anyway. Moreover, most Post Offices remain open. In fact, uncertainty of stock markets, pound, dollar, euro etc, might even lead to an increase in activity and prices, especially at the higher (serious) end, as the lockdown forces people to retreat to their personal hobbies, and will free up more time to tune in to online auctions.

Think of the top row as coins 1 2 & 3 from left to right, and then the bottom row as coins 4, 5 & 6 from left to right:- Move 1 - move coin 4 to rest under and between coins 5 & 6 Move 2 - move coin 5 leftwards to rest underneath coins 1 & 2 Move 3 - move coin 1 to between coins 5 & 4 voila !!!

The weekend looks like becoming warm and sunny - so at least we can get out into the gardens for something other than gardening. Maybe sit in the Sun for a while.

Well that is good news. Let's hope they extend the ban nationwide. The Chinese are utterly barbaric in their treatment of animals.

From London Coins Signature sales - The Michael Cole collection - about half and half pennies and halfpennies, but there look to be some interesting halfpenny varieties.

Victoria's smoking knee has got a lot to answer for.... I agree with you, Richard. It would be good if the posts concerned (including our two) got moved to the pictures thread. There's nothing wrong with any of them, except they're just not in the right place. Maybe one of us could message @TomGoodheart to do this.

Have you got "Talking Pictures TV"? - many many old British films, and TV series, including comedy's.

One can only tell the truth and one can only lie. You don't know which one is which, and nor do you know from the information given, whether either robot knows whether the other one tells the truth or lies. In that scenario, if the one telling the truth is asked that question, then he will truthfully answer, I don't know, meaning you still have a 50 50 chance. If you ask the one who's lying how the other would answer it wouldn't matter what door he pointed to, you would still have a 50 50 chance.

Precisely - we don't know because that factor is not built into the equation. If it is, then your answer is obviously 100% correct.

You meet three Gods on a mountain top. One always tells the truth, one always lies, and one tells the truth or lies randomly. They are called Truth, False and Random. They understand English but answer in their own language, with ja or da for yes and no - but you don’t know which is which. You can ask three questions to any of the gods (and you can ask the same god more than one question), and they will answer with ja or da. What three questions do you ask to determine who’s who?

Correct.

The "other robot"? According to the rules as posted, you can only ask one, ergo: you will never know. The riddle is not capable of being solved.

Here's one for you:-

Logically, nothing. You will never know which of them is the liar. Pure Russian roulette - you might as well choose yourself.

Just back on this point alone, may I suggest you contact Dix Noonan & Webb, after taking a look at the pictures on their website. Their photos are not only superb, but can be enlarged to whatever size suits the viewer, without any loss of clarity. I'm sure your business would increase by many orders of magnitude if you were to follow what they do, as collectors would know exactly what they were attempting to buy. I'd also suggest you take a long hard look at your grading, which is a tad generous, and your pricing structure, which is more than a tad steep for sometimes quite mediocre stock.
