Hi all, I'm back again. Exams just finished, hopefully I'll get my 99+ :) Anyway, I have been wanting to show you guys this coin for a longgggg time, like months, so I hope the verdict doesn't disappoint me :) Grease strike through or something is that what they call it? I'm not sure.. Sorry about the picture, I only have a really bad scanner, any bits that look black arent black.. Let's just take it as metallic silver :) Posted link below, and it's nice to see you all again, hope I didn't miss much. http://img69.imageshack.us/i/scan0911121856.tif/Oh and btw I can faintly see the outline of Queen Elizabeth, its pretty cool :) Edited by justabeginner

In case you missed it in the other post,  BACKI would have to say from the picture that it looks like someone has taken a grinder to it. Are the rims even with the fields or still raised? Good to see you back again. |

Rims are even with fields, fields are kinda like you know up and down wavy feel to it... And yes I did catch your message thanks again though :)

Is it much thinner than a regular 50¢? I'm thinking it might be a split planchet.

It is thinner, but not much, its like you shave off the rim and you get the thickness of my coin... :)

back justa... I'm inclined to agree with Sap, it looks like a split planchet. How does the thickness compare to other 50¢? life is a mystery to be lived not a problem to be solved

Split planchet or very low pressure trial strike. Or someone has ground it down. Eliminate the grinding down possibility, get it weighed on scales accurate to at least 0.1 of a gram. If it's more than 0.2-3g lighter than 15.55 g then it's ground down or a split planchet. If it's a split planchet there'll be some characteristic roughness on one side of the coin as per the coin in this blog article: http://www.australian-threepence.co...-part-2.html If it's underweight and doesn't show this roughness then it's post mint damage.

Hey nancy, nice to see you again. Thanks mark for the comment. Unfortunately, no scales with me. :( Anyway, if it helps, have you guys ever held a 3-d card, where if you turn it at different angles and different pictures come out? This coin is kinda like that, accept different levels of reflectiveness, it looks as though it's been composed of different metals. Thats as best as I can describe it. There are characteristics patterns of mini lines all going in one direction in several places, I don't think its dings on the fields cause it goes in one direction. If it was indeed a split planchet or low pressure strike, is it common or uncommon, and how much would it be worth? :) Thanks for everything.

Actually, where in the picture you can see like a black area, thats where the different level of reflectiveness is.

That's a very good photo that Markn posted of the split planchet coin showing the rough internal grain with high and low points.  I think a sanded coin would bring the whole surface down to one level, with smaller scratches here and there, in possibly many directions. |

Yep.. mine doesn't look as extreme as that unfortunately, might be grinded I don't know.., but perhaps there is a less extreme case of a split planchet? I still have hope left :D
