A factual, no-hype guide to what currency revaluation is, how it differs from redenomination, which currencies RV collectors follow, and how to authenticate the notes you buy.
Currency revaluation (RV) is a deliberate, government-set change in the official value of a country's currency relative to other currencies. Unlike a floating exchange rate that moves with market supply and demand, a revaluation is an official policy decision by a central bank or finance ministry to adjust the pegged or managed value of its currency upward.
In collector and enthusiast communities, 'RV' most often refers to the long-held expectation that certain undervalued currencies — principally the Iraqi Dinar (IQD) and the Vietnamese Dong (VND) — may one day be officially revalued upward, increasing the redemption value of notes held by collectors.
Revaluation and redenomination are often confused, but they are fundamentally different. Revaluation changes a currency's exchange value — one Dinar becomes worth more Dollars. Redenomination does not change value; it only relabels it, replacing old high-denomination notes with new lower-denomination ones so that 1,000 old Dinars becomes 1 new Dinar with identical purchasing power.
This distinction matters to collectors because a redenomination does not increase the wealth of a note holder. A revaluation, if it occurred, would. No central bank has announced a revaluation of the Iraqi Dinar or Vietnamese Dong; redenominations have occurred in other countries (such as Zimbabwe and Turkey) without enriching existing holders.
The Iraqi Dinar (IQD) is the currency most associated with RV collecting, owing to speculation that Iraq's post-conflict economic recovery and oil reserves could lead to a future upward revaluation. The Vietnamese Dong (VND) is the second most common, based on similar expectations tied to Vietnam's growing economy.
Zimbabwe dollar notes — particularly the 2008 100 Trillion Dollar note — are widely collected as well, though these are valued as novelty and historical artifacts rather than for any revaluation expectation, since Zimbabwe abandoned its own currency in 2009 and reintroduced it in 2019. Other historically devalued currencies, such as the Venezuelan Bolívar, are collected on similar grounds.
RV currency is a speculative collectible, not a guaranteed investment. No government or central bank has announced a revaluation of the Iraqi Dinar or Vietnamese Dong, and any such decision would be a sovereign policy matter outside the control of any dealer or collector. Buyers should approach RV currency as a long-term holding they are comfortable keeping regardless of outcome.
Authentication is critical. The market for revaluation currency has historically attracted counterfeiters, so buyers should purchase only from sources that provide serial numbers, ship physical notes, and can tie each note back to its order record. Third-party grading through PMG (Paper Money Guaranty) offers an independent authenticity guarantee.
Every banknote carries a unique serial number assigned by its issuing authority. For RV collectors, that serial number is the note's fingerprint and the foundation of provenance — the documented chain of ownership from the issuing mint to your collection.
At Always Currency, the exact serial number of each note in your order is recorded and printed on your receipt at no charge for orders of 10 notes or fewer. This lets you photograph the note, verify it against grading databases, and register it with confidence that it is the very note you paid for — an essential safeguard when buying speculative currency.
Currency revaluation, often abbreviated as RV, is a deliberate change in the official value of a country's currency relative to other currencies or to a benchmark, set by the issuing government or central bank. In collector communities, 'RV' commonly refers to speculation that certain undervalued currencies — most often the Iraqi Dinar and Vietnamese Dong — may be officially revalued upward at some future date.
The Iraqi Dinar (IQD) and the Vietnamese Dong (VND) are the currencies most commonly associated with RV collecting. Zimbabwe dollar notes — including the 100 Trillion Dollar note — and certain other historically devalued currencies are also collected, both as novelty items and as historical artifacts.
Revaluation changes a currency's exchange value relative to other currencies — for example, raising what one Dinar is worth in US Dollars. Redenomination does not change the value; it replaces old notes with new notes that have fewer zeros (e.g., 1,000 old Dinars becomes 1 new Dinar) while keeping total purchasing power the same. RV collectors seek the former; redenominations do not increase a holder's wealth.
There is no guaranteed return. Currency revaluation is a government decision, not a market event, and no central bank has announced a revaluation of the Iraqi Dinar or Vietnamese Dong. RV currency is best treated as a collectible and a speculative holding, not a guaranteed investment. Buyers should only spend what they can afford to hold long-term.
Authenticity is verified through security features on the note (watermarks, security threads, color-shifting ink), comparison against central bank reference images, and third-party grading services such as PMG (Paper Money Guaranty). Recording each note's serial number and tying it to a receipt provides an additional layer of provenance.
Revaluation currency can be purchased from specialized currency dealers and collectible banknote marketplaces. Always buy from a source that provides serial numbers, ships the physical notes (not a certificate), and can trace each note back to its order.
