Construction quality

BU, i.e. Brilliant Uncirculated, refers to the Silky finish used by Hungarian numismatists. These coins are usually not put into ordinary circulation, although they are produced using the same technique in terms of their production process. The manufactured pieces are not handled with bare hands, but are placed directly in a container or capsule, thus avoiding that the coins collide with each other during processing and cause scratches on each other.

During the Frosted Proof process, the coin is immersed in an acidic medium so that its entire surface has an icy effect. After that, the coin's motifs and protruding parts are carefully polished so that they are mirror-like.

Matte is an intentionally non-reflective surface used on certain coins. This is achieved by sandblasting the material before the curing process.

Matt proofs have a more restrained beauty compared to PP, but at the same time their soft, satin surfaces are rich in texture and depth.

Matte proofs are similar to circulation coins in many respects,

The PL, or Proof-like, coin is produced using a special minting technique. Similarly to PP coins, with the difference that they do not have the icy effect and here minor errors are allowed due to the minting process.

The mirror beat, i.e. PP, is an abbreviation of a word of German origin, Polierte Platte, but in English we usually call it the Proof process.

The name comes from the fact that the background of the coins made with this process - to put it crudely, the non-protruding parts - is like looking into a mirror and seeing ourselves in it.

Commemorative coins, which are not normally put into circulation, are made with this technology and their mintage is low. Pieces intended primarily for collectors are made in this way.

The brochures and leaflets issued for commemorative coins are important sources of information about the coins. These publications usually include the coin's history, description, design, and issue data. In addition, they often contain information about the coin's creation, production process and material. The brochures and leaflets issued for commemorative coins are a valuable source of information about the coins. These publications can help coin collectors, historians, and anyone interested in coins.

In numismatics, a replica is a coin or banknote that is not an exact copy of an original piece. Such replicas generally do not have the same value as the original coins, but are popular with collectors because they offer the collectability of an original coin at a more affordable price. Replicas are often copies of past coins, but there are also modern replicas.

Their dimensions, material, other numismatic parameters, and even their medal image can often be different.

The quality of making replicas varies and they are usually not of the same quality as the original coins.

RP, i.e. Reverse Proof, is similar to the Proof process, only inverse to each other in terms of the appearance of the coin.

While in the PP process the background of the coins is mirror-shiny, in the RP technology the coin motifs, that is, the protruding parts, are mirror-shiny.

Commemorative coins, which are not normally put into circulation, are made with this technology and their mintage is low. Pieces intended primarily for collectors are made in this way.

The U.S. Mint has occasionally produced and sold coins that differ from those in circulation. The main difference is the surface used when minting the coins.

They appear matte, unlike their PP counterparts, which have reflective surfaces. They are generally of better quality than coins intended for mass circulation.

Certificates used in numismatics are documents that confirm the origin and authenticity of a coin or other numismatic object. These certificates are usually issued by independent expert organizations who are competent in the evaluation of coins and numismatic objects. When issuing limited edition commemorative coins, the mint also issues certificates. Numismatic certificates offer many advantages to collectors. First, a certificate can help protect collectors against fake coins and other counterfeits. Second, a certificate can help increase the value of a coin or other numismatic item. Third, a certificate can facilitate the sale of a coin or other numismatic item. This makes numismatic certificates an important tool for collectors, as they help ensure the authenticity of coins, their value, and help avoid the disappointment of counterfeit items.
