Where Is Your Collection Going After You Pass Away?

I'll probably give it to my younger sibling(s) or my children.

I will have it BURIED WITH ME IN MY MASSIVE TOMB.

As I've said elsewhere on the subject, coin collecting is a disease that only infects about 10% of the population, and it is not usually hereditary. So unless you're either fortunate or have a larger than average pool of heirs and successors, there isn't likely to be anyone who is interested enough in the collection to maintain it and keep it going.

Which may not necessarily be a bad thing, especially if your collection is a considerable proportion of your estate. If you've got, say, five heirs, and only one of them is a coin collector, do you show favouritism to that one in your will and give your entire collection to them? That sounds like an excellent way to either cause a family rift or to have your will challenged by the four neglected heirs. The "fair" solution is to have it sold and divided evenly; if one or more of your heirs wants to buy part of your collection, they'll have to pay fair market value for it out of their share of the estate.

Logically, it would be far better for you (and for family harmony) if you disperse your collection while you are still hale and hearty. This has the added benefit of sharing your knowledge and explaining to your designated inheritors the significance of your most prized items. Alas, not all of us are given that chance and many of those of us who are given that chance refuse to take it, remaining collectors to the very end.

Then sell today, because you might be gone tomorrow. You don't get to choose the timing.

Considering the sheer mess that my room looks like, and our ongoing plans to eventually move out of our current country before it becomes too much of a dystopian hellhole (and, for that matter, our export laws, which don't look kindly on leaving the country with lots of old coins... even if they're mostly old foreign coins) I won't be surprised if I lose my collection well before I pass away.
Also, I believe in the Singularity, so I do not intend to die of old age anyway.

That said, assuming the collection is still with me by then, I do expect that I'll eventually find some relative who would like it (perhaps a kid or grandkid of my younger brother; at some point, it looked like the brother himself is interested, but now that he's 9 he doesn't seem to be as interested anymore - of course it could still change later).

I voted "other" because you don't have an option for "who cares, I'll be dead"

I enjoy it. It relaxes me, it gives me a feeling of pride and satisfaction and really, after I am dead, who cares where it goes. I know I won't.

Hopefully be able to sit in the auction room with a cold beer in my hand and laugh at the stupid amounts it will all bring. Then when the auction firm cheque clears, give all of it to the SPCA. It will be my way of saying what great joy animals have given in this life.
If this doesn't work out ...............honey there all yours enjoy!
