Value Of Gilted (Gilded) Silver Coins In General

The interest in the UK in gilded decimal coins appears to be marginally above zero.

When the jubilee sixpence came out in 1887 the new reverse did not have a value stated, only a crowned shield inside a garter. Some people gilded these and passed them off as half-sovereigns. The reverse design was promptly changed back to include the value. One of these would be of great interest.

Re the damage question, it is difficult to be exact. I suppose it would depend on the rarity of the coin and the rest of its condition.

If something is damaged, a rule of thumb is that it is priced at 1-4 grades below the original coin, depending on the kind and severity of the damage. A small mounting mark on the rim is minor. A hole through the centre is severe. Obviously bullion value comes into play, and if a coin is excessively rare and desirable, it may retain more value.

Modern severely damaged coins I just throw away for the good of the hobby.

Thank you for the greatly varying input/advice.

I posted the actual coin I used in the example for the dent and gilding. Since it's a 1758 sixpence that seems to be AU or higher, would the gilding make it worth 10% or 80% of the actual value (of a same coin without the gild)?

Thank you all for your input! Decided not to buy it. Uncertain about it's value.
