Yep, I hear you.
I am not a collector, i play my drums but yeah, sometimes
I do purchase a drum that doesn't get played much and I usually
end up thinning those out over time.
Personally, i think congas are kinda silly to collect, they are large and heavy.
stamps would be a much easier thing to collect

Anyhow, my 12.5 king is part of a 5 king set I am building up,
2 of them are in near mint condition
(many photos online and possibly here of those drums)
and the other 3 are going to get restored to match....long term project.
Here's the (2) I am speaking of:
