What Comic Books are Included in the SCPI?
The following principles were considered when selecting comic books for the SCPI index.
1) Select books that are frequently traded. This provides more data. Also, these issues have greater relevance to the market since they represent what more collectors are trading.
2) Select key issues. This tends to create the same list of candidates as the first criterion. Key issues have much higher numbers in the CGC census and thus generate more trades.
3) Select books that have values in the range of greatest relevance to "rank and file" collectors.
This last criterion requires explanation and I'll admit, that some decisions that I made were arbitrary.

In the post What is your most valuable Silver Age Comic book worth?
I shared the results of a survey of Silver-Age Collectors with regard to their ten most valuable Silver Age books. The results are shown below. As I explained in the previous post, there is a large population of collectors whose "best book" is worth $401 to $3000. Similarly, these collector's "next 9" most valuable books had an average value of $201 to $2000.
Based on these results, it seemed the most practical to choose issues for the index with values in the range of approximately $200 to $3000. In fact, the actual samples, as shown in the table below span a range that slightly exceeds these bounds.
A study of the table above shows that the issues selected span the range of $177 to $3311. Of the issues selected, 68% are worth less than $1000. I did this in order to best represent the typical "top 10" of the average collector from the survey (with a median value of $700).
So many times, I've read about the phenomenal increase in value of a near-mint Action #1 or some other "Premier" comic book. I chose to steer away from this with the SCPI. I hoped to create an index that represented "middle class" or "rank and file" collectors. Besides, I suspect that every Premier collector with a few books worth $30k and up also has books worth in the SCPI range of $200 to $3000 in their CGC boxes or file cabinets. Finally, from a practical point-of-view, those Premier books are traded too infrequently to be useful within a price index.
By tracking the middle to high-value books, I'm believe that I have made an index that is relevant to the majority of collectors. Let me know what you think!
