Depicts a half-length portrait of Milton Friedman. To the left of the portrait, in two lines, the inscriptions "MILTON FRIEDMAN" and the years of Milton Friedman's birth and death, "1912–2006," are visible. At the bottom right edge, the engraver's privy mark is placed in the center.

Depicts a hand balancing a pencil. Above the depiction of the pencil, the formula central to Friedman's reinterpretation of quantitative monetary theory, describing the equation of exchange, "M×v=P×Q," is visible. In three lines below the depiction of the pencil, the inscriptions "HUNGARY", the denomination, and "FORINT" are placed. Slightly below, in two lines, the issuance year "2022" and the mint mark "BP." are featured.

Friedman's reinterpretation of quantitative monetary theory, expressed by the equation "M × v = P × Q," explains the relationship between money supply and economic activity:

• M (Money Supply): Total money in the economy.
• v (Velocity of Money): How often money circulates.
• P (Price Level): Average prices of goods and services.
• Q (Quantity of Output): Total goods and services produced.

The equation shows that money supply times its velocity equals the price level times output. This means changes in money supply or its velocity impact prices or output, highlighting the importance of money supply in economic activity and inflation.
