    Decimal Pennies - Variants and errors

    in Decimal Coins

    Posted

    David Groom's book shows that there are three, perhaps four reverses for the 1971 Business Strike Two New Pence. Do these also apply to Proof examples?  If so, I think the attached is the Reverse C (Two additional incuse lines to the top of the left hand plume) but can anyone confirm what, I think I'm seeing,  that there are also two vertical incuse lines down the right hand side of the quill he mentions, or are these light reflection?  Cliff

    Point to ponder:  "1971 2P coin (new pence) Rare" currently on sale on eBay for £120, having been reduced from £135.  Low grade with no explanation what makes it rare (except just the price perhaps?).  Am I missing anything?

    Grease fill ??

    Thanks for the response - suppose if grease was going to stick anywhere it would be in the small indentations needed for the rivets and border beads.  Do you have any suggestions for the lines across the middle of all the horizontal bars of the portcullis?  They don't show on my close ups, only on the full Rev shot (when zoomed up a bit). I've had a play at trying to replicate the shot but without success to date.  Think they may have something to do with my cocked eyed photographic skills(?) or highlighting my lack of.

    Another interesting one. Here the H is to the left and in contact with the linear circle, so it's top most part is practically underneath the 8.

    Do you know how they described this H to the left Mike?  Yes, the H to the right is mine.

    Wow, nice pictures there. On the 1849, the colour appears to be metal oxidation - too late for organic solvent rescue. I agree, have to leave it alone but at least you tried. 

    The second piece almost appears as though some liquid dropped on surface with secondary oxidation. 

    Thanks for all your time and trouble Vicky, not to mention your willingness to share your knowledge.  Reckon I owe you a beer.

    NO RUB, please.

    Update - don't know if my cleaning attempts did any good but don't think I'll try anymore.  There is some pitting within (because of?) the stained/flecked area but, as with the flecking and purple stain, hardly noticeable in hand under natural light.  Other than these 'metal defects?' the coin detail,fields and rims are high grade, even taking the 'pothole' by the trident handle into consideration.

    I have never been shy about good acetone and a quick tamp down.  Problem is that the skin oil is,as I understand it, breaks down by bacterial action with organic acids that oxidize the surface metal. 

    Still worth it as some of the oil and metallic compounds that are generated can be removed, some even after longer exposures....the metal underneath is usually not terribly altered. 

    Thank you Vicky, your advice and prompt replies are much appreciated.  I'll have a go on a small area with acetone and cotton buds to see if I can bring about any improvement.

    Thank you all for your speedy and highly knowledgeable responses. I'll take comfort from what you've said, suffice to put the wire wool and abrasive paper away!

    Vicky, if the purple palm prints are skin oil, is it possible to clean it off without damaging the coin or will it have reacted or etched itself into the surface?  Sorry to be a nuisance but my mentioning wire wool and abrasive paper is a good indication of my complete lack of knowledge on the subject!

    Thanks again

    Strange colouring on the reverse, Cliff. Any idea what happened? 

    'Fraid not Mike.  Both the dark specs and purple tinge seem to be from within the metal rather than on the surface and hardly noticeable in the hand under natural light.

    I use a digital microscope for my photographic attempts which, alas, does distort colours and is apt to give a blueish to things.

    I confess I'm dubious about trying to see if anything cleans off, especially as the stains, to me, appear to be in the metal itself. Any thoughts please?

    Following recent discussion regarding re-cut dates.  I reckon the attached displays a re-cut 4 (bodged repair?) and wondered if this then qualifies as "a variety" and has anyone seen this before?  My pics are at their usual low standard so would like to confirm that there is a serif (although faint/filled) over the I in GRATIA.  would like to hear your comments please.
