This would really be an awesome idea if that comes out as planned. You seem to be consistently giving out some cool ideas but most of them doesn't get implemented as planned right from the report badges to YouTube Videos. May be you are the only one working on scripting and codes and your busy schedule is pushing these ideas to an unknown future date.
I was thinking that it might be cool to produce a limited run of 50-300 coins and give them out
Why is the number ranging from 50-300, isn't it pretty low for such a huge forum? Are there only 300 reputed members? May be you could give around 1000-2000 coins to all those willing to expose their location to you primarily since most of them remain anonymous. Also what would be the purpose of giving someone a collectible coin (which might be quite rare) if they doesn't know what it is?
Does this sound like a good idea?
Of course YES. Some coin makers like Kialara who has insane levels of thinking in designing collectibles take a little higher time than expected, anyways planning soon would be better so that the coin can be announced exactly on November 22, 2019 18:04?
What features would make the coin especially interesting?
A pre loaded one or a DIY coin should be the primary aspect of a bitcoin collectible. The private keys should be controlled by you/other treasurers of this forum. Like others said, may be we can take on the poll for best designs after the maker has released few of his ideas to the public.
What's the best way to get a coin like this made?
May be you can give away the coins to the top contributors to this forum and other small contributors can probably be awarded with a
polymerbit note? That could be better actually. There are quite good coin makers in the market right from Kialara, CryptoImperator and others whom you can hire to bring the best out of their minds to commemorate the 10th year anniversary.
So basically only Chipmixer campaigners get it?
What makes them superior from other users of this forum? Posting quality? Oh man, what has posting quality to do with collectibles?
Each coin to be specially designed as per each user's UID and have their UID engraved in it. Or even better, engrave the user's avatar and name on one side, and a default bitcointalk logo, or anything that exclusively defines bitcointalk on the other side.
Also if possible, load the exact amount of satoshis/ ubtc/mbtc equivalent to the merit/post count of the person receiving it?
That's certainly a very bad idea. It would become a hectic work for the coin maker or probably the coin will never come out actually! It should be of similar patterns with numbering from 1-1000/2000 and giving them out on the basis of account age of the user. For instance if the user registered on 2010 they would be receiving the first set of coins and later on.
