<p>I have a physical bitcoin which has a 8 digit number. Is it possible to get the address of the coin without paperwork, as none accompanied the coin when a family member gave it to me. 
I also have a Blockchain.info wallet and it says "Scan Pairing Code". When I do that, it shows little blue dots and takes a photo.
Can you tell me if I need the letter or address that comes in paper form?</p>

It would help to identify the coin (and therefore how to use it) if you edit your question to include sharp photos of both sides of the coin  with a ruler next to it for scale. Black out any numbers in a photo editor before uploading.

# Finding the address of a physical coin

(Asked by: username_0 on 2018-06-28)

I have a physical bitcoin which has a 8 digit number. Is it possible to get the address of the coin without paperwork, as none accompanied the coin when a family member gave it to me.
I also have a Blockchain.info wallet and it says "Scan Pairing Code". When I do that, it shows little blue dots and takes a photo.
Can you tell me if I need the letter or address that comes in paper form?

The first step is to identify the specific type of coin and what company created it.

See [Coindesk - 10 physical bitcoins](https://www.coindesk.com/10-physical-bitcoins-good-bad-ugly/) - If your coin looks like any of those, you can find out whether it has any value and how to use it.

There are many variations:

* Many physical bitcoins are novelty items and have no value.
* A few may have some intrinsic value from the materials they are made of (gold, silver etc). I imagine most do not.
* Some physical coins have an associated bitcoin value which can be redeemed if the company that issued the coins is still in business and honest. For example, Titan bitcoin say:

  > If you ever want to spend or transfer a 2FA coin’s bitcoin value, simply peel back the coin’s security hologram and enter the redemption code on our website, along with your registration info.
* Some physical bitcoins have a private key concealed inside them or under a tamper-evident sticker. You can probably type that into a bitcoin wallet to import the key. An example is the discontinued
  series-1 **Casascius Coin**

  > How they work: The "private key" is on a card embedded inside the coin and is protected by a tamper-evident hologram. The hologram leaves behind a honeycomb pattern if it is peeled. If the hologram is intact, the bitcoin is good. If you have purchased a 2-factor item, the private key is encrypted and will need to be decrypted using your original preselected passphrase before you can redeem the funds.
