1958 Half Penny variants

[bhx7]

Hi All

Looking for a little advice. I have started putting all my half penny coins into order and also sorting through the variants. I have about 30 + of 1958 but am struggling to assign the 3 variants. Are there any easy ways of descerning the variants? The first variant is quite easy to find its the F & G that I am find more trouble with. Any help would be appreciated.

Thanks all

Brian

Simplest way, if you have all three types is from the thickness of the rims and the size of the teeth on the reverse. Put simply, Rev E has a thick rim, Rev F a thin rim and Rev G one in between. As far as teeth go, Rev E has short teeth, Rev F has long teeth and Rev G has teeth sized in between.

Thanks Dave. Will give it another go. May take some pics and post them when I think I have cracked it. Is it rev G that is the hardest to find?

Thanks Brian

pictures of each reverse will help

Here are a couple. I can't seem to find the ones with the thinner rims that I put to the side. I think they would be variant F. These I think could be E & G. Will put close ups of the rim on next post.

A Slightly more standard coin. The teeth are smaller again in relationship to the rim

I looked at these variations some years ago, and sort of came to the conclusion that there might be four types , though the differences are so slight that it's hard to be totally sure, any way I scanned all of them and placed sections of all four together for comparison .    Terry

1  has a narrow rim with the shortest teeth

2  slightly longer teeth with slightly wider rim

3  is very similar to 2 but the teeth do seem a fraction longer

4  has the longest teeth and widest rim

Thanks Terry, seems to be lots of differences, all of which are very small. Makes it very hard to discern the different varieties after reading your comments it makes just that little more complex. I definitely have found more than 2 size of teeth on the wide rim version. Will revisit the coins and try and keep a more uniform image set and see what I find.

Thanks Brian

As you can see from my findings , I only found one length of tooth on the wide rim type , so I would like to see some pics of the two types, if possible, as that would bring the total number types to five   Terry

I counted and reverses E, F and G all the same number of denticles (144 for the curious).

Terry am totally starting from scratch. I can identify the E variety easily with the long teeth a major give away. However, still trying to get the F and G sorted out. If I am right so far I am finding the E the least common and think the G the most common but not 100% sure if I am getting the F & G right each time. I am going to persevere and see what I find. I will post pics and conclusions once I am happy I have things right.

Right half way through my fine to AUnc 1958 halfpennies and have found at least 5 different teeth to border variations. I used percentage size of tooth to border ratio and found the following from the first 12 coins : 70% x 1; 75% x 5; 85% x 3; 94% x 1 and 102% x 2 (give or take 1%).  I believe the 94% teeth to rim coin to be a Type G and the 102% with teeth larger than rim Type F. I maybe well off but would appreciate any input.

There is definitely lots of variation.

Sorry I've  not answered sooner, only she indoors took me on a rest  from the pennies , something called a holiday .  Anyway  I digress , it seems some kind of experimentation was being undertaken by the mint during 1958 . I'm  not sure of the types my self ,as the wide border type according to Freeman should have short teeth , where as I find them to all be longer. Gouby states that he can find no difference in the types , and so has not listed them.  There clearly are a few differing types. You and I must keep looking, and see if we can find all of them.    Terry
