You added tokens beside the same objects. The amount of game money changed. The number of objects did not. More money and more things are different changes.

Output means the goods and services people produce. Goods are things, such as toys. Services are work done for someone, such as repairing a toy. Money can pay for them, but adding money does not itself produce them.

When spending money grows faster than available output, it can put pressure on prices to rise. Buyers may be able to offer more for the things available. That is one way broad price rises can develop.

Your auction is much smaller than an economy. Bidders can keep their tokens or dislike an object. Bids might stay the same. Record what happens rather than correcting it to match a story. The useful comparison is between the changed budgets and unchanged objects. Then ask what might differ if more objects were made too.

Paper tokens are easy to count. Real money is not all paper. People also use money recorded in bank accounts. Adding printed notes and changing the wider money supply are different things.

In the United States, the Bureau of Engraving and Printing makes paper currency. The Federal Reserve has a different job: conducting monetary policy. Monetary policy means central-bank actions that influence money and financial conditions.

Inflation is a rise in the general price level across an economy. It is broader than one toy becoming expensive. Your two auction prices cannot measure inflation for a country.

So why not solve every shortage by making more notes? Notes are ways to pay, not extra bread, homes or repairs. Yet a real explanation needs more than "printing always makes everything dearer." Production and spending can respond too. Follow what was held fixed in your game, and keep the wider economy’s many changes in mind.
