It will create a mess on the secondary market where people are not as familiar with the details. You will have people selling unfunded as funded 1 BTC to unsuspecting buyers, you will have buyers find out later the 1 BTC casascius coin they bought actually has no btc in it even though the seal is intact, you will have mass confusion from the market and put in doubt all the old coins including those from previous years if they actually all have btc in it.  It will destroy the integrity and reputation of casascius coins.

I am 100% against selling 1 btc coin with seals without actually have the listed btc in them (that's actually committing fraud) or allowing buyers to apply the seal themselves( for obvious reasons ).  Both horrible horrible ideas.

If that's how it's going to be going forward, please use a different design and don't call them casascius coins.
