Complete set of 1987 Dimensional Drift trading cards, NM condition, I need to talk about these $450 (Febberling Gardens)

I have a complete 1987 Dimensional Drift Series 1 trading card set. All 220 base cards plus both holographic chase cards (the Convergence and the Unraveling). Near mint condition. Kept in penny sleeves inside a binder inside a box inside a room that I maintained at stable temperature and humidity for nineteen years.

I need to sell them because my daughter needs braces and apparently teeth are more important than preserving what is, and I will die on this hill, the most significant card set ever produced in the modern era. Series 1 was printed during an ACTUAL minor dimensional drift, which means cards 144 through 167 have a slight iridescence that isn't part of the printing process. It's from the event. You can't replicate it. The Grading Bureau won't even acknowledge it because they "don't grade for ambient phenomena" which is a COWARDICE that I have discussed at LENGTH in the collector forums.

I'm also including a signed card #78 (The Cartographer) signed by Elmore Denn, who designed the set. The signature was authenticated in 2019 by someone who has since lost their authentication license for unrelated reasons, but the signature is real. I was there. I saw him sign it. He used a blue pen and then he said "don't sell this" and I said "I won't" and here we are.

$450. That is below market for a complete set with both chase cards and a signed 78. I know this because I have been tracking market value in a spreadsheet for eleven years. Don't come at me with a lowball.
