Wow this is a very interesting discussion going on here with many "heavy hitters" in MCC knowledge weighing in with excellent insight and opinions. All of the SS members have really conveyed brilliant view points !!!
Before I get into the view from my perspective on varieties let's all look at what the definition of "collectible" is as that is what we are all doing here, we are amassing a collection of Modern Chinese Coins from a variety of metal composition, dates, mints, etc. Varieties are an extremely interesting part of that collection and in my opinion varieties are also important to serious collectors, appearing in many types of items that people collect.
collectible also collectable
1. That can be collected
2. Worthy of being collected
A collectable or collectible (aka collector's item) is any object regarded as being of value or interest to a collector
[1] not necessarily monetarily valuable or antique
[2] There are numerous types of collectables and terms to denote those types. An antique is a collectable that is old. A curio is a small, usually fascinating or unusual item sought after by collectors.
[3] A "manufactured" collectable is an item made specifically for people to collect
I agree with Peter and I am very fascinated by varieties. Whether it be "large date", "small date", "frosted", "mirrored", etc. I am very intrigued by varieties and compelled to collect them all.
Of course the reasoning behind some varieties is easily apparent such as date sizes we all know that the majority of those date variations are attributed to the fact that the coins where minted at different Chinese mints such as "large date" may have been the Shanghai mint whereas "small date" possibly the Shenyang mint or the "frosted bamboo" at the Shenzhen Guobao mint while the "mirrored bamboo" at the Shenyang mint. These types of variations are more easily explainable as the coins in question where obviously minted in completely separate locations at completely different mints.
Now when the attention is focused on a coin such as the one in this discussion the S10Y 1993 "frosted" variety I'm not so easily convinced it can be written off so quickly (as some have done) as simply "worn dies". I'm not saying that this "die wear" hypothesis is completely without merit but when you look at these coins side by side you see one that is heavily frosted and one that is completely devoid of any frosting whatsoever. I have yet to see any of these 1993 pandas with varying degrees of frosting, not to say that they do not exist but I have not seen any. In my opinion this variance (frosted/non frosted) was done intentionally. How will we ever know for sure? Will the Chinese mint produce this information? I don't think so because they do not have it. The mint barely recorded actual mintage numbers accurately so logically the Chinese mint has even less information on varieties. If this is the case then we can only rely on the information we have attained through personal experience and that of those who know much more than us.
If we (collectors) were to rely solely on information from the Chinese mints, we would know much less than is currently known as it has already been established that the Chinese mint(s) reporting/record keeping of mintage and varieties has been less than stellar, almost nonexistent. If not for knowledgeable and studious authors/researchers such as Peter Anthony, Shen Jiaju, Ge Zukang, Ron Guth, Nick Brown and several others, we as collectors of Modern Chinese Coins would know very little to nothing.
According to The General Manager (in 1988) of China Gold Limited "Shen Jiaju" in his commentary in the book "Modern Chinese Commemorative Gold & Silver Coins and Medals-Volume #One 1979 to 1988, it was not until the 1970's that the issuance of Chinese coins made use of various techniques such as frosted designs on mirrored fields to strike bullion and commemorative coins on materials such as silver, gold and platinum. In considering that the 1993 frosted pandas were minted within 20 years of when frosting was initially used in minting MCC, it is not outside of the realm of possibilities that the Chinese mint was still in an experimental phase and possibly purposely minted a predetermined amount of these S10Y 1993's in a frosted and non-frosted finish. As we all know with MCC anything is possible, I wouldn't rule anything out. This was likely done on many other MCC and surely not pandas alone.
It's only my opinion but the assertion that NGC revels in and promotes varieties for profit doesn't hold much weight as in the case of pandas for example I could not find any silver pandas that actually have a variety attribution fee associated with them. Here is the NGC link and it reveals that none of these varieties (including the 1993 variety) have any charges associated with their attribution.

There are no gold pandas as well that have any fee associated with their variety attribution

If NGC was attempting to profit an additional $12 per coin here are 150 various pandas in the two links above that they could be charging attribution fees on but they are not doing this so I really don't see NGC support/promotion of varieties as a profiteering escapade. Why can't it be as simple as NGC is just as interested in the mysterious discoveries in MCC that continue to develop and are there to listen to and support their clients the collectors?
Modern Chinese Coins have only been minted/created during the last thirty years an infinitesimal blip in time when compared to other world coins that have been around for 100's or 1000's of years but amazingly so little is known about them. A highly knowledgeable collector/investor of MCC once said this at a coin expo in Hong Kong
"A few years back, all too many people regarded all modern Chinese coinage as little better than Franklin Mint medals. Many Chinese coins were melted for their bullion content (some still are!). Now just about every person who admits that they melted these coins regrets it, as coins that used to number in the thousands are now nearly as rare as carrier pigeons" This above statement along with the known fact that the planned mintages of many coins from 1979 to 2009 was nowhere near the actual mintages sets the stage for many MCC's to possibly be very elusive in the next twenty years. Even those thought to be common today.
So I am collecting/recognizing any variety that is discovered. Who knows truly and conclusively what is still left to be discovered and exactly its rarity?
Basically it all boils down to the fact that it is your choice to either recognize/collect varieties or not. I have friends who say there are too many varieties so they only collect one coin of each year while others (such as me) are fascinated by all varieties and attempt to collect them all.
Collect what fascinates you and enjoy your collection

Ok so I put my son to sleep then poured myself a glass of wine and finished my third glass upon finishing this post I know it randomly went off topic but hopefully there is some logic in there somewhere !
