Hello, maybe you can enlight me, I search the information about how much 2011 1BTC brass series 2 where made, and I don't find it anywhere
From the Casascius Bitcoin Analyzer, 1799 coins from 2011 are series 2. Leaving 4567 from 2011 as series 1.
Meaning if this is accurate s2 is substantially more rare for a 2011 coin.
http://casascius.uberbills.com/?page=charts&year=2011Those values do include all denominations of coins, not just 1BTC.
The 2012/2013 charts give a similar ratio for s1/s2.
Though I don't recall having seen a 1BTC s1 for these years in person..
