You are talking about people with serious amounts of money !! No " normal " person ( no offence ) could afford to spend £4,000 on a tin ...more than once in a few years surely.
I don't think its Collectors in the true sense of the word ...OMO ...I think its people with vast amounts of money. Not up at the crack of dawn at boots, fairs etc swapping their way up to ' better ' items. Or selling loads of smaller finds to fund that special purchase.
I am not having a go good luck to everybody however to get your stuff, its just a different animal in a different world. One of my mates often poses the question " how good would your collection be if you were a multi millionaire ?" In my case it would be non existent cos if I could just buy any thing I wanted I would honestly get no enjoyment out of it.
A few big players or any way a small percentage are dragging up prices to unprecedented levels, will they keep rising, level off or even fall................thats the $64,000 question.
Its certainly not a one way bet as many suggest. Guinness, Doulton, Blue & White, Stamps etc, etc in general could point to going in the wrong direction
