Colin G. Posted June 26, 2012 Posted June 26, 2012 Just thought I would share an image of this 2p coin from a 1973 proof set, which has toned rather brightly!!The coin is still sealed in the set so has not been tampered with, if anyone wants the set for £100 I am willing to sell and they can get the 2p slabbed, it must be worth £1,000 to a toning collector!!

Haha - the awful 1973 sets! The £100 price would be for an UNtoned set, of course. That really is a notorious year for the proof set - it may be due to something in the red dye used for the foam insert. The weird thing is that some sets have survived with no toning at all, and I'm hanging on to mine! Quote

Though quite why some exposure to air would cause such ugly toning is a mystery - many proofs live out of sealed cases and never get toned. Quote
SEnumis Posted June 27, 2012 Posted June 27, 2012 The same has happened to my 1973 proof set (only 9 hands 50p). I don't know why it should be. There was an oil crisis at that time and I wonder if the smelting process for the bronze was skimped somehow (does anyone know if the Royal Mint's furnaces were oil fired?). I think it is a fault of the metal rather than the air because the cupro nickel coins don't have the same problem. Quote

You should have seen the 10p and 5p I took from a 1973 set I'd bought in an auction lot - I only got rid them by selling them at face value to buyers of other proofs. They were absolutely hideous.

Suppose it was a combination of the red dye, and not properly sealed cases. Where the cases are properly sealed, there is no reaction. Like your set.Possible ? Quote
1949threepence Posted June 27, 2012 Posted June 27, 2012 Just as a matter of interest, how long did it take for the 1973 sets to get so badly toned ? I mean, they can't have been like that when they were first bought. I'm given to understand this was 1976, as opposed to 1973. Quote

I'm given to understand this was 1976, as opposed to 1973.I'm no chemist Mike, but I guess that's as good a theory as any. I never saw a '73 set until the 90s (only had the '70, '71, '72, and '77 sets before that), and that's when I picked up a horribly toned one from an auction lot. I then found out it wasn't rare by any means. But no, they wouldn't have been sold in that state - you're right, it was around 1976. The '73 sets may have been minted a bit before the '74/'75/'76 sets which were issued together. I'm thinking the '73 set may have been a bit earlier because of the commem 50p. Quote
