What does that mean? Are you trying to get an idea of what percentage of coins produced are different from "normal". People ask about population all the time- there are no mintage figures on anomalies, whether they're die varieties or any other type.
On some varieties, we can estimate a probable population- like the 1995
DDO, I believe it had a full die life and produced many hundreds of thousands of coins. That's why it's a $25 coin, it's very plentiful. But as for exact figures- there'll never be a precise, or even approximate count.
In what I do, I'm constantly trying to get a fix on how rare a coin is, it has everything to do with value- supply and demand. I've handled some modern varieties that are exceedingly rare, with less than 30 examples known. Some examples of varieties that are this rare are the 2006
DDO #3, the 1994-P Class V
DDR, the CAMs of 1992 etc. The KNOWN examples are the only way to figure their rarity. What "might" exist has no bearing on what is known to exist. Some varieties are indeed so rare that there can be an approximate number known, but when there's more than 50 or 100 of them, nobody tracks the existence of every single example.
Furthermore-
TPG populations are of benefit only to those wanting to get a general idea, they are in no way conclusive in regard to population. Many of a variety aren't slabbed, but raw. And sometimes a
TPG's population can be greatly inflated by people cracking out the coin and resubmitting it in an attempt to get a higher grade. In other cases, like the '94
DDR is recognized and attributed by ANACS only.
So, if I understood what you were asking 1913-V, there is absolutely no way to get a fixed population on any specific variety, just estimates.
