Toning on Proofs - Question

ozzie101

I understand that toning on coins is a matter of preference for most collectors with some liking it and others wanting a coins w/o any toning at all.

Would light toning on proofs lead to a downgrade by the grading services or a lack of interest in the coins by other collectors?

The toning "appears" to be because of 'normal' coin ageing and not any environmental damage or from PVC - the coins are no longer brilliant .........

Also in the event of the toing being from the above, would there be any time frame that the damage would appear? The coins are about 50 years old...

Both toned and untoned are can be gorgeous... here's a dollar and a dime from the same original proof set.

Toning on proof coins can affect the grade downward at the TPGS, especailly if it can hide imperfections in the mirrors.
When it comes to collector interest, it depends on the color and the deepness of the toning.
If the toning is super deep trying to remove the toning could ruin the look of the coin.

Toning can add to or detract from a coin's eye-appeal and even its grade. Some collectors buy only toned coins, others buy only color-free ones and still others buy both.

Beautiful coins!

The toning on the coins in question has no color.....would that knock the coin from say for example a Proof 69 to a Proof 68...????

Toning without color sounds more like what is described as haze or a film over the white surface. This would usually distract from the appearance of the coin and therefore the grade... particularly in very high grade proofs.
