So these are not designed to be bearer instruments like BTCC or Casascius coins/blocks, just some stick on raised letter strips to show what's meant to be their actual block mined and rewards value, which don't sound at all tamper proof to me

I'm not sure I understand.... the 2020 Bitcoin Blocks are indeed bearer instruments (once funded by the mining pool).
The only difference is that we are selling and shipping it empty, and then later, it'll be loaded by the mining pool.
Yes, as for the full look and feel, to see the final block height and amounts, there will indeed be a DIY step.
These details and everything else will indeed be properly explained once we launch the product.
We talk about tamper-evident, and not tamper-proof. (or are you referring to some other aspect of something being tamper proof?)
The only true tamper evident component of the block is the sticker covering the encrypted private key, and the BIP38 passphrase underneath the scratch-off part.
The raised lettering showing the block height and block reward BTC amount is a display nicety, as in the end, it's all about what the balance shows for that address on the actual blockchain.
I'm only giving you a preview here, and sorry for not clearing on all of the details during this "tease" phase. (Hope the forum members here appreciates the early access information here.)
thanks,
Bobby
