I don't recall this being discussed on here, but GPA is reporting a sale of an 8.0 Tec 33 in March, 2017, for $150k. If I'm not mistaken, that was a sale through Metropolis. That is simply astounding.
I'm also seeing a 6.0, Tec 31 selling for $175k in March, 2017, and a 7.5 Tec 35 for $119k in Feb, 2017.
Also, a restored, coverless, married, incomplete copy of Tec 33 just went of just shy of $2k the other day on eBay.

These books have simply exploded this year.
