Continued to experiment with the following designs.....
MONERO/BITCOIN COIN

MONERO/BITCOIN/LITECOIN/DOGECOIN

Yep...I have 8 Private key water proof papers behind that holo...had to dig deep into that coin!
Also threw in there a metamask seed for a wallet with an NFT just for kicks!
BIP38 COIN
![](https://ip.bitcointalk.org/?u=https%3A%2F%2Ftalkimg.com%2Fimages%2F2023%2F05%2F14%2Fblob16c1aff24a8068ef.jpeg&t=663&c=2wcnhpJjOKsBYQ)
This uses Mike Caldwells tech with BIP38 encryption...so you have the private and public key on the outside...behine the hologram is the QR code for the private key and also a 32 alphanumeric password to decrypt the encrypted private key. According to https://www.security.org/how-secure-is-my-password/ it will take billions of years to crack it. I also placed the same BIP38 paperwallet on an online digital stamp back in 2017 loaded with 0.02BTC and it has yet to be cracked! http://www.crypto-stamps.com/private3.html
5 YEAR ANNIVERSARY COIN FIRST CRYPTO STAMP MAILED
![](https://ip.bitcointalk.org/?u=https%3A%2F%2Ftalkimg.com%2Fimages%2F2023%2F05%2F14%2Fblobe229461abf78bed0.jpeg&t=663&c=E7aBwTDWor_lEg)
This commemorative coin has two holos...in the back is the private key for loaded BTC and also the seed for a metamask wallet for the NFT for this coin.
The front has a cypher stamp hologram wallet seed for an NFT for the first crypto stamp mailed and also the first digital crypto stamp.

MULTI HOLO/MULTI SHARE SHAMIRS SECRET 2/3 ONE COIN
![](https://ip.bitcointalk.org/?u=https%3A%2F%2Ftalkimg.com%2Fimages%2F2023%2F05%2F14%2Fblob06f4930c0a1aa359.png&t=663&c=nHjNsVUbunFwZQ)
I adjusted the front size and made larger font...hologram now filles the front nicely.
3 SEPERATE 2/3 MULTI SHARE SHAMIRS SECRET COINS

This time I made 3 shamirs secret coins with each one having its own individual share behind the hologram. So 3 coins and take 2 shares to unlock the private key in order to sweep the bitcoin.
