Well, I thought Supporters had a slightly different arrangement, but I guess not, and I can't find the "terms" of being a Supporter, so sorry 'bout that, and I withdraw my offer.
I did not think your "offer" was really real because that probably would have been a technical violation. I looked at it as a good natured reply as to the worth of the coin and your spontaneity and unpredictability to purchase such a coin should the coin be offered for sale in the correct forum. Based on the foregoing, I do not see an "offer" that can be accepted or withdrawn.
Grease filled die, what we term a "greaser". It's a pretty nice example, these normally fetch $2-3 at least....it all depends on how many design elements are missing.
