以照片来分析,其实并不是最佳的,因为即使同一枚硬币,在不同的光线下、不同的角度、不同的数码相机、不同的人……拍出的照片有时会有不同的感觉,观察不同照片的细节有时会给人带来误解。这很常见,很正常。要以实物为根本,抓住最明显、最确切的差异来分析,排除拍摄或扫描等因素的干扰。硬币,如果显微观察,也许每一枚都有很小很小或很明显的区别。机制硬币,作为工业产品,难以避免这个差异问题。中国的很多金银币章都有这类问题,有的熊猫银币,多达几十个版本,并不稀奇。如果你能准确翻译和阅读我在这个帖子中的每一个词和图片,这将会减少你的疑问。

这个帖子中的照片,除了1984年原版古塔铜章是我自己的藏品并自己拍摄的外。其它照片均是搜集自网络,都是别人的藏品和照片。

类似银币,这两枚都是真币,右边的那一枚,“断线”
注:照片来自NGC,但原照片偏色严重,颜色偏黄并发虚,下图是经过校对颜色等处理过的

I understand.  Limitations of photos vs viewing in person.

1985牛金币三种不同版别(均为NGC评级币)(注:此金币的“颐和园”的“颐”字写错了,正确的字左边不是“臣”字,金币少了一竖)
注:照片来自网络,对原照片进行过校对颜色

RareMedal- very nice!    Is there any agreement on which of these varieties of 1985 Ox are the most rare?

I'm pleased to find raremedal a fellow frosting enthusiast!
I would call the first picture the "original intent".  It is very hard to find!  The one displayed by raremedal is the best example I've seen.  The small wavelet at the tip of the red arrow is barely discernable in most "original intent".  The 2nd picture has multiple sub varieties.  The fading of the wave feature is progressive.  The third picture by raremedal is not the end of progression.  The picture below is the worst case. (e.g., NGC 3429002-027).  It is not rare, 8 out of the 39 in my database.

After studying frosting variations and fading features in MCC for the past 2 years or so, my enthusiasm for it has waned.  There are just such an abundance of them in MCC, and I don't have enough money to buy the whole spectrum of progression even in the cheap Historical Figures series.  I tend to buy the best and the worst examples nowaday.  What I did noticed along the way is the best, or "original intent", is frequently the hardest to find.  It is the one with most completed, well-defined features and generally has the best eye-appeal.  Knowing what is the "original intent" and collect them is probably what I should focus on in 2013.

Is this a final answer?  Real silver graded pagodas are genuine except for a few silver plate that passed thru NGC?...........

回复:SANDAC

硬币图案的不同,原因:有的是模具磨损造成,有的是压力不均造成,有的是不同模具造成,有的是压铸中途修模造成,有的是手工喷砂不同造成,有的是小模翻大模造成……。很多新中国金银币可以找到许多不同。比如《古代科技发明——指南针》几种规格材质的大小币,会发现许多细节的不同。“路漫漫其修远兮,吾将上下而求索”

Raremedal,
Thank you for your insights and encouragement.  I no longer buy minor variations with irrational exuberance, but I continue to study them and buy key variations when I find them.  I will post my findings here on CCF, and I will also summarize these variations with a photo collage such as below (1993 Peacock silver 10 yuan).  These photo collage are stored in CCF Gallery:
