Edward VII Coins at BSJ - How Did the "Biggies" Fare
Diaconis replied to VickySilver's topic in British Coin Related Discussions & Enquiries
@jaggy very interesting Fullerton pattern sixpence soon up for auction at Künker. A beautiful rarity with interesting history. https://coinsweekly.com/counterfeited-coins-or-not-counterfeited-coins-that-is-the-question/ I read with interest of Matthew Young’s role in the creation of the patterns. I’ve a couple of coins that have passed through his hands. Always good to connect some dots. (I’m sure that the recent discussion on how best to handle the other half after a hefty purchase will be useful to the lucky winner. Methinks the €10,000 reserve will be blown out of the water.) -
Coin aquisition of the week.......
Diaconis replied to basecamp's topic in British Coin Related Discussions & Enquiries
Yes Asda, i think you are correct. I can see traces of unbracketed serifs which replicate the form of the overstruck ‘I’. thanks -
Coin aquisition of the week.......
Diaconis replied to basecamp's topic in British Coin Related Discussions & Enquiries
Hello, Here's an interesting oddment which I spotted this morning. Has anyone seen one before? There is an overstrike error I/(?) in BRITANNIARUM and it is not mentioned in ESC or Davies. May have been given a light clean at some time, not sure, and also not mentioned by the seller. I'll be able to judge better when in hand. (Sold as AU but it looks a higher grade to me). Thanks. -
oh, the tides they are a-changin. (sorry, carry on)

Paddy, it's called Photoscape X (for Mac) and it is free.

Paddy, thanks for the tip, it works great, lots of possibilities (found it in the Mac store ) Just couldn't resist quickly trying it out, here's a plugged, decapitated, and 'defe(e)ated' obsidional Pontefract shilling, very intuitive, don't need to read a book👍 thanks, Paul

Made me smile. Remember those innocent good old days, before the plague really took hold ⚰️ (couldn't find a perspex coffin)

Came across this website the other day, The Old Currency Exchange. MB1 left a comment on Sept 16. Clearly was aware of 1933 penny and the various forgeries. Her command of English was better back then😉 https://oldcurrencyexchange.com/2014/08/20/rare-coins-the-1933-british-penny/#comments

Can't think of a more endearing theme for a coin collection. Not for the savvy Investor. -
1897 one penny high tide variation
Diaconis replied to chris's topic in British Coin Related Discussions & Enquiries
Mike is probably spot on here, (no pun intended) humidity and acids are the cause. A chap in China made a study of the effects of sweat causing pitting corrosion on brass coins using synthetic sweat. Here's a snippet which might be of interest. "Corrosion behavior of brass coinage was investigated in synthetic sweat solution by electrochemical measurement and surface analysis methods including scanning electron microscope (SEM) and energy dispersive X-ray spectrometer (EDX). It is indicated that chloride ions in sweat solution accelerate the anodic active dissolution of brass, which is the main reason for pitting corrosion and dezincification corrosion. Meanwhile, lactic acid and ammonia water also promote the anode reaction. The corrosion products on the surface are mainly composed of basic copper chloride, cuprous oxide, the complex consisting of urea in association with copper, and few lactate ions. The kinetics of pitting corrosion development obeys the following equation of J0=0.3735(t+185.93)−1/2, and the process is controlled by the dissolution of salt deposited on pit surface." So, it would seem that if your coin is dehydrated then, the brake is on for pitting. 'Handle with gloves' and keep them in a very dry environment would seem the way to go here. -
Wow, now there’s £+7000 worth of fakes sold.

Could just be the awful toning but I'd want to see this one on the scales before I bought it, my scales that is😉 https://www.ebay.co.uk/itm/123849889017?ul_noapp=true "t is a superior collectors coin with a superior tone one for the big boys and LADIES and is worth every penny "

Yet, “I never clean any coin dirt is age tone and patina and i always handle them with gloves on A nice coin for any collector” 🤭

The seller states 1 available, I wonder which one you’ll receive. There are two examples photographed.

They say Oscar Nemon’s design wasn’t exactly flattering but if this uniface example hadn’t Churchill’s name in legend you’d be hard pressed to identify who it is.

I added one to basket and the RM will add a Peter Rabbit BU 50p free of charge. Don’t all rush at once. -
Far from being a penny aficionado, I had to read a thread from 2013 to see that F90 is a narrow date. In that post RCL35 had just picked one up in Chicago and various estimates were bandied around at that time ranging from £2.5k to £10k. Just out of curiosity how many examples are known to exist of this type, roughly speaking?

Interesting clip Numismatics’ nemesis, Numistacker again. What a surprise.

I’ll wager that it is the efforts of the Predecimal contingent, via Ebays worst, that gave them the idea. 😉 -

A part of me wanted to believe. Reminds me, whatever happened to the chap who was going to detect on an old property where a coin collection was reputedly buried?
