Yes, I am finding the above to be true more and more frequently. I have also found people see dollar signs and an easy target based on what I show.
Here is a peek behind the curtain... I entered the hobby a few years back and saw a small window of opportunity to scoop up a lot of pieces I personally enjoyed, but also believed I would be priced out of the market if I didn't act quickly. This proved to be true, so I am grateful for the timing. I sold my comic collection during the pandemic when prices on books were crazy high, thinking books couldn't sustain because of quantity and art would because of the rarity. My strategy with certain art pieces was to overpay slightly in particular situations in which it was necessary to sweeten the pot enough to entice reluctant sellers in hopefully a win-win for both. This was a deliberate strategy for a season with the awareness it was not sustainable long term unless the art market continued to grow exponentially. I reluctantly sold a few big pieces to cover my initial seed capital in respect to both comics and OA and now enjoy a zero-debt collection.
I think I have around 50% of my collection posted, but I made the decision to save new uploads for reveal during the live shows I sometimes do with Bill and Dinesh. Dinesh's reveals are typically epic, so I need to ensure I have some way to be relevant when we all get together virtually.
Even in light of the above, I still plan to post the majority of my pieces at some point. I like sharing and connecting with people who share similar enjoyment whether it be first appearance collecting or specific characters involved.
In response to one of the other mentioned of "overpay posts", I have definitely seen a few of those regarding pieces I've grabbed; but I love what I buy and research a ton.
