1970 S Small Dates Vs Large

From the PCGS web site:

While there are no known records offering the numismatic community hard numbers on the exact number of 1970-S Small Date Lincoln Cents for either the business-strike or proof format, estimates point to their representing approximately 10% to 15% of the total issue mintage, if not less. With a total mintage of 690,560,004 for the 1970-S business strikes and 2,632,810 for the 1970-S proofs.

This suggests that perhaps 60 million to 70 million business-strike examples of the 1970-S Small Date may have been released while approximately 250,000 to 300,000 of the 1970-S Proofs are of the small date variety. Of course, not all these coins have survived decades of circulation and other common forms of numismatic attrition, leaving still significant but decidedly smaller quantities for collectors today.

The two major varieties of the 1970-S Lincoln Cent are distinct enough that both the large date and small date pieces are collected by most of the dedicated Lincoln series enthusiasts. The 1970-S Small Date is also included in virtually all PCGS Registry Sets involving series runs of the Lincoln Memorial cent. Thus, collectors have many options for incorporating this variety into their holdings.

Thanks @nfine for the info. The PCGS estimate is a lot more than I expected.
