accepts for evaluation all certified or raw coins, tokens and medals.
NCS can remove contaminants such as PVC, soils, tarnish, carbon spots,
verdigris and encrustation from the surface. NCS does not perform
repairs or mechanical alterations of any kind. Removing detrimental
material from the surface of an item may dramatically improve its
appearance and eye appeal. This service is designed to further preserve
the originality of the material only and prevent the damage that can
result from contamination that is left untreated.
NCS接受對所有評級幣、章或裸幣、章送
往評估，NCS可以從幣面上移除PVC（聚氯乙烯）、泥土、沾污、碳斑、銅綠、水銹等沾染物，NCS不會對錢幣進(jìn)行任何機(jī)械性修補(bǔ)（見后文），從幣面上移
除這些有害物質(zhì)可能顯著的改善幣的外觀和品相。這項(xiàng)服務(wù)也可以進(jìn)一步保護(hù)原本的材質(zhì)，避免因?yàn)槿魏螞]有處理的沾染物繼續(xù)侵害錢幣。BENEFITS OF NCS CONSERVATION
NCS錢幣保養(yǎng)的優(yōu)點(diǎn)Rare
coins are like no other collectible. Steeped in history, each possesses
a unique background and historical context that captures the
imagination. First-time enthusiasts, serious collectors, and
professional coin dealers, all involved in numismatics, find great excitement in discovering the qualities that make each coin special.
稀有硬幣和其他收藏品截然不同，走進(jìn)歷史，每一枚幣都擁有獨(dú)特的背景和歷史文化。不管是首次收藏迷、嚴(yán)肅的收藏家或者專業(yè)幣商，所有在錢幣界的人士都可以在發(fā)掘一枚幣的特色時(shí)得到很大的滿足。Over
time a coin can change in appearance due to environmental conditions,
mishandling and natural forces of decay. You can take an active role in
preserving coins for future generations to admire by contacting
Numismatic Conservation Services (NCS) so that NCS’ specialists may
assist quickly in identifying damaging conditions, and professionally
conserve and stabilize your coins.
隨著時(shí)間遷移，一枚幣可能因?yàn)榄h(huán)境因素、錯誤的處理或者自然損毀而改變其外觀。聯(lián)系NCS（錢幣保養(yǎng)服務(wù)）可以主動保護(hù)你的硬幣，NCS專家會協(xié)助迅速的判斷損毀程度，并專業(yè)的保養(yǎng)和穩(wěn)定你的硬幣。The
expertise of NCS technicians has long been needed in numismatics. Not
to be confused with undesirable cleaning, proper numismatic conservation
involves examination, scientific analysis and a reliance upon an
extensive base of numismatic knowledge to determine the nature of a
coin’s state of preservation and the extent of any damage. NCS is
uniquely qualified to meet the conservation needs of the hobby.錢幣收藏界極需要像NCS技術(shù)人員的專業(yè)能力，不同于不受歡迎的清理，合適的錢幣保養(yǎng)包括檢查、科學(xué)分析和依靠強(qiáng)大的錢幣知識來判斷錢幣狀態(tài)和任何損毀的程度，NCS具有獨(dú)特的服務(wù)以滿足有關(guān)保養(yǎng)的需求。The Nature of Coins
錢幣性質(zhì)Eight
metals are primarily used in minting coins, tokens and medals:
platinum, gold, silver, copper, aluminum, zinc, tin, and nickel.
Platinum and gold are considered to be durable and stable but not
impervious to damage. Silver, copper, aluminum, zinc, tin, and nickel
are more susceptible to environmental damage to their gold
counterparts, with tin being the least stable metal. Most coins are made
of alloys. Gold and silver, for instance, are usually alloyed with
copper. Metals may corrode when in contact with acidic materials
and excessive moisture and heat. The effects of corrosion appear
differently on each metal or alloy. Tin becomes white and scaly, and may
crumble away in your hands. 八種金屬經(jīng)常被使用來鑄造幣章：鉑、黃金、銀、銅、鋁、鋅、錫、鎳，鉑、黃金被認(rèn)為是耐用和穩(wěn)定的，但不能避免損壞。銀、銅、鋁、鋅、錫和鎳等，相對于黃金來說，更容易受到環(huán)境的影響而損壞，其中錫屬于最不穩(wěn)定的金屬。大多硬幣均由合金制造，比如黃金幣和白銀幣通常含有一定的銅。當(dāng)接觸到酸性物質(zhì)或過量的濕度和熱力時(shí)，金屬可能產(chǎn)生腐蝕，其腐蝕的效果在不同金屬或合金上不盡相同，錫會產(chǎn)生白色的鱗狀銹，并在你的手中碎裂。
Light
surface corrosion, or toning as it’s described in the numismatic
community, can be very desirable. Collectors often prize it as one
indicator of a coin’s originality, or closeness to its original state.
Toning causes copper coins to turn brown, and silver and nickel
coins to develop hues of blue, red, green, purple, and other colors.
Often, these coins need little or no conservation; however, advanced
stages of corrosion can damage a coin’s surfaces. If the toning process
goes too far, the coins turn black and the actual surface of the coin
may be ruined forever.
輕度表面腐蝕，或者稱為“年久變色”（也稱氧化/包漿）可以是很受錢幣界歡迎的，收藏者認(rèn)為這種銹
色顯示了幣的原始狀態(tài)。氧化可導(dǎo)致銅幣變成褐色，銀、鎳幣則發(fā)展成藍(lán)、紅、綠、紫和其他顏色，通常這些幣只需要很少的（甚至不需要）保養(yǎng)，但是，更深的銹
蝕會損壞幣的表面，如果氧化過程進(jìn)行的太快，錢幣會變成黑色，幣的表面也會被永久破壞。Professional
coin conservators are no less skilled and responsible than conservators
in other fields, so it is time to re-evaluate the cleaning and
conservation of coins in this new light. Cleaning removes dirt and
agents that hide or might be harmful to an object’s natural
and original state. Proper cleaning takes into account original
materials and finishes. It studiously avoids damaging original materials
and finishes. The overall appearance is enhanced and the coin is more
likely to last.專業(yè)錢幣保養(yǎng)師的技巧和責(zé)任心并不比其他領(lǐng)域的人士差，因此，現(xiàn)在可以重新評估錢幣的清理和保養(yǎng)需求。清理可以清除掉可能對幣的自然和原始狀態(tài)有害的污垢等物質(zhì)。合適的清理需要考慮原來的材質(zhì)和拋光，并刻意的避免損壞。整體外觀因此得以提升，
而硬幣也更能持久保存。The
professionals at NCS are skilled in conservation techniques that can
prolong the life of the coins in your collection and, as a side benefit,
often enhance their appearance. Combining knowledge of materials
science with extensive numismatic experience, they strive to the fullest
extent possible to return your coin to its original appearance. NCS專業(yè)人員精于保養(yǎng)技術(shù)，這可以延長幣的生命，作為一種附加值，通常也提升了他們的外觀。結(jié)合材料科學(xué)的知識和大量錢幣知識，他們盡最大努力以還原你的硬幣到原本的外觀。Sometimes
confusion arises about the term "conservation." Numismatic conservation
involves examination, scientific analysis, and a reliance upon an
extensive base of numismatic knowledge to determine the nature of a
coin’s state of preservation and the extent
of any damage. Conservation also encompasses appropriate procedures to
protect the coin’s original appearance and to guard against future
deterioration to whatever extent possible.有時(shí)候客戶會對“保養(yǎng)”一詞產(chǎn)生誤會，錢幣保養(yǎng)包括檢查、科學(xué)分析和依靠強(qiáng)大的錢幣知識來判斷錢幣狀態(tài)和任何損毀的程度，保養(yǎng)同時(shí)包含了采取適當(dāng)措施以保護(hù)硬幣的原本外觀，并盡量防御將來的敗壞。Professional
conservation should not be confused with "Coin Doctoring", in which an
attempt is made to improve the appearance and grade of a coin through
deceptive means such as artificial toning and where unaccepted or
unorthodox methods are employed. Also not qualifying as conservation is
restoration where mechanical repairs are made such as filling holes,
smoothing out scratches, and re-engraving of detail. It is essential to
speak with an NCS professional:專業(yè)保養(yǎng)也不應(yīng)該和“錢幣治療”混淆，其嘗試使用欺騙性的手段如人工氧化或其他不被認(rèn)可的、非正統(tǒng)的方法以改善錢幣外觀和評分。另外，錢幣修補(bǔ)也不等同于錢幣保養(yǎng)，其使用填補(bǔ)空洞、磨平劃痕、重刻圖案細(xì)節(jié)等機(jī)械性修補(bǔ)。以下情況可以向NCS專業(yè)人員咨詢：when you notice changes in a coin, such as discoloring or spotting
當(dāng)你注意到一枚幣的改變時(shí)，如變色或出現(xiàn)斑點(diǎn)等before you try to conserve a damaged coin yourself
在你嘗試自己保養(yǎng)一枚受損錢幣之前if your coin has been subjected to extreme environmental conditions
如果你的錢幣曾遭遇到極端的環(huán)境條件影響after you have submitted a coin to a grading service and had it returned with a "no grade" designation for certain reasons such as "PVC," "artificial toning" or "Residue."
在你呈報(bào)一枚幣到評級服務(wù)后，被退回來不予評級，其原因是由于“PVC”、“人工氧化”、或“殘余”的相關(guān)參考鏈接： http://www.ncscoin.com/conservation/index.asp
