The 4 year time frame you are looking for is going to be tough with just a 10% over since there is about 5%+ of value of forks on those coins and the value of the collectable itself.
The Fork-value is closer to around 2.5% of the Bitcoin value. But since collectibles have to be physically delivered, I doubt this is what OP is looking for.
Did a quick calculation of BCH+BSV+BTG and came up with a bit over 2.5% ($875 at the time) and then just figured the dozens of the other crap forks would add together to get to about the same.
If it's worth the time to someone to put in the time, and if they have the ability to track down all the odd wallets and small exchanges to get value for the forks is going to vary person to person.
Anyway, the main reason I can see needing it is to prove you have "been in the game" for a while.
Trying to impress the newbies so to speak. If it's for a scam or just to posture would have to be seen.
