  1. Did anyone here have a look at, or bid on, or even win!, any of the gorgeous Ancient Greek coins in this sale?

    I placed a 'highest estimate' bid on a few of the more modestly priced  items, hoping I might get one of them. But after the first few lots I knew I wouldn't - everything went for at the very least 5 times estimate, but more often 10 times, and in one or two cases even more ... one lot was estimated £2k - £3k, but went for £40,000!!

    I do find it difficult to to believe that a  100 year old  high grade coin can remain untarnished when left undisturbed in a draw or similar for most of that time as the other  silver items I have start to tarnish after 3 months of so unless wrapped in sulfur free tissue paper.

    It's a good point. I have double florins and two JH crowns where the fields look highly reflective, but not polished, and the designs and legends aren’t (not cameo but definitely not very reflective like the fields). It does make you wonder how they have maintained that state.

    The Al foil and Sodium carbonate/Bicarbonate convert the toning, mainly silver sulfide,  back to metallic silver .Whereas Goddards' probably etches the surface to remove the silver sulfide. Personally  given the chemistry I prefer the Sodium carbonate/ Al foil method as despite the people who like toned coins the truth is toning is corrosion is damage to the surface of the coin whereas the the sodium carbonate / Al foil is returning the silver to the coin's surface.

    From Goddards own site:

    How Silver Dip Works:

    1. Chemical Reaction:

    As tarnished silver jewellery is immersed in a silver dip solution, a chemical reaction occurs. Thiourea or potassium thiocyanate in the solution reacts with the silver sulphide, which is broken down into one component, silver, and one component, sulphur.

    2. Dissolving tarnish:

    The silver sulphide dissolves into the solution as the chemical reaction proceeds, leaving behind a transparent, untarnished silver sheet. During this process, the tarnishing process is reversed, revealing the shiny silver surface underneath.

    No mention of 'etching'?

    Does your coin exhibit the closed 'H' in 'FARTHING' as well?

    That's the one feature I don't take seriously - the farthing legends are so small, and the serifs so pronounced, that effects like you're seeing on the H are almost inevitable. The bifurcation on the other hand is a very definite effect of something happening on the die.

    Thanks Peckris 2 for responding.  It would seem that if your example exhibits the 'closed H' in 'FARTHING' then the dies are likely the same. In addition, my example contains a bifurcated inner circle above the 'I' in 'FARTHING' (see image below).  Should this feature also appear on your example, it would appear the dies are identical, except that my example is in a somewhat later state.  Of course this analysis may prove incorrect, and I may be obliged to go back to square one and start again...

    The lower part of the bifurcated inner circle eventually terminates in the field.

    I've just looked, and my example definitely has the bifurcation near the I so it's clearly the same die.

    The forth magnified image indicates that both the ‘1’ & ‘8’ are triply entered and the ‘6’ is doubly entered.

    The fifth magnified image seems to indicate that the date may be of the 'wide type' as both the '1' is far from the '8' and the '2' is far from '6'.

    All thoughts welcome.

    Interesting. The date on yours is almost identical to mine. However, the non-wonky underlying '1' (yes clearly double punched on yours) is not - or barely - evident on mine, whereas the doubled 8 is, so is the 'twin tailed' 6, and the width of the numerals. It would seem to be the same reverse die.

    I would leave it myself. The coin has a bit of wear and you can't be certain if there is lustre underneath. I wouldn't think it's worth the risk of dipping.

    If you did dip, I have a golden rule:

    1. use Goddards, and a clean container

    2. dip FOR ONLY 10 SECONDS

    3. remove, rinse thoroughly, and dab dry with a clean towel

    If that doesn't cure the problem, or at least only partly, don't be tempted to dip again.

    If I found a Harry and Megan 50p I would just use it, even if it was worth more. Terrible people.

    If even half of what's in Spare is true, then it's The Family - or rather the structure around them - that's terrible, not so much the Sussexes.
