We BuyOld(BOB)!

When the till's empty, the sale's OVER!

Older coins, bigger cash!

Priced by the year your coins last moved. Every year older pays about 1.5× more! Coins that moved on or after Jan 28, 2026 don't qualify.

What's your stash worth?

Type in your (BOB) address. Your browser reads the public chain from explorer.dobbscoin.info and adds it up. No obligation, and nothing is sent to us!

1. Get your free appraisal above, so you know what you're getting.
2. Send your coins straight from that address to the number below. One address per sale, and don't shuffle the coins first: moving them resets their age!

   How do I send FROM one address? (Read this! A normal send grabs coins from all over your wallet.)

   1. Back up your wallet.dat first. Always.
   2. In the Dobbscoin wallet: Settings → Options… → Wallet tab, tick Enable coin control features, click OK. (Don't see it? Your wallet's too old. Get the current one at dobbscoin.info/dobbscoin.)
   3. Go to the Send tab. There's a new Inputs… button. Click it.
   4. Click Tree mode. Your coins are now grouped under each address. Make sure ONLY the box next to your old address is ticked (that ticks all of its coins). Click OK.
   5. Paste the buyback address above into Pay To and type the amount.
   6. Selling only part of the pile? Tick Custom change address and paste your same old address, so the rest stays there.
   7. Send. Then on the Transactions tab, double-click the send to see its Transaction ID. You'll need that next.
   Everybody sends to the same address? How do you know which coins are mine?

   1. Every send is its own transaction with its own transaction ID, right there on the public chain. Ten sellers make ten different transactions.
   2. The chain shows where the coins came from. Each transaction lists the address it spent from. That's how we know they're your old coins, and how old they are.
   3. Your signature proves it's you. The message you sign in step 3 names YOUR Gnosis address and YOUR transaction ID. Only the holder of the sending address can sign it, and nobody can swap in their own payout address without breaking it.
   4. Each transaction pays once. Somebody who spots your deposit on the explorer and posts its transaction ID gets nothing: they can't sign for your address.
3. Sign the one-line message with the address you sent from. In the Dobbscoin wallet it's File → Sign message. Fill in where you want your xDAI and your deposit's transaction ID, then copy the message exactly. Your Gnosis address for the xDAI Your deposit's transaction ID
   Fill in both boxes.
   Copy message
4. Post the transaction ID, your Gnosis address and the signature as a reply in the WE BUY OLD (BOB)! forum thread. Once your deposit has 60 confirmations (about 2 hours), we check it and pay you!
