Using hobbies as a source of cash requires a slightly different mindset than collecting as a pure hobby. Here are a few areas requiring mental adjustment.
将你的兴趣爱好作为金钱的来源要比纯碎将收藏品作为爱好持稍微不同的心态。下面需要调整心态的一些方面。

Understanding the market
了解市场

As a buyer, you already have a baseline understanding of your collectible's market, but sometimes the seller's perspective is very different. For example, is there any reason to believe your collectibles will appreciate or depreciate in the short term?Talk to other sellers and do online research to determine proper pricing and recognize trends and value.
作为一个买家，你对该收藏品的市场应该已经有了基本的了解，但是有时候卖家的视角往往是不同的。比如，是否有足够的理由让你相信你的收藏品在短时间内会升值或者贬值？经常和卖家进行交流，在网上做一些调查来正确估价，了解行业的发展趋势以及投资价值。

Removing emotion
斩断感情

Can you really sell that antique doll handed down from your grandmother, or the rookie card of your favorite baseball player? If you can, will you be able to place a realistic price on it?
你真的能把你祖母传给你的古董娃娃和你最喜欢棒球运动员的新手卡卖掉吗？如果你可以，你能够给它们一个真实的估价吗？

Authenticity
真实性

You may not care if you can prove your autograph of Marilyn Monroe is authentic. A buyer will care very much.There are many good resources and references online to help you judge authenticity and direct you to professionals in your chosen collectible field.
你可能不在乎你是否能证明你的玛丽莲梦露签名的真实性，但是买家会非常在乎的。在网上有很多很好的资源和参考能够帮助你鉴别真假，或者你可以直接选择你收藏领域的专业人士来判断。

Condition assessment
状况评估

All collectibles are condition-sensitive, and one of the hardest things for collectors to do is to assess objectively the condition of their beloved collection. For items like coins, stamps and sports cards, there are objective guidelines and professional grading services. Other fields may require you to find online examples for reference.
所有的收藏品都是条件敏感性物件，对于收藏者来说最困难的事情就是客观的评估他们心爱的收藏品的状况。一些收藏品，像硬币，邮票和运动卡片，有客观的参考和专业的等级服务。其它领域的可能就需要你在网上找一些参考案例。

Scarcity
稀缺性

The baseball card industry almost killed itself in the late '80s and '90s, cranking out cards as if they were Argentinian pesos from that same period. It took the card industry about seven years to recover fully.
棒球卡行业在八九十年代末的时候几乎将自己陷于绝境，粗制滥造的卡面好像他们就是来自同一时期的阿根廷比索。卡片行业花费了大约7年时间才完全恢复。

Most modern collectible producers cannot restrict supply enough to maintain value. For older collectibles, scarcity is not usually an issue — but just because something is scarce does not mean it is valuable.
很多现在的收藏生产商不能限制供应足够的东西来稳定价值。对于较老的收藏品，稀缺性通常不是什么问题，但是也不是仅仅因为稀少就意味着这个东西就是有价值的。

Whatever you collect, take the time to do diligent research before you start to sell. Look for professional organizations and trade magazines. They will help you properly value your collectibles and find the best places to sell them — whether it is on eBay, local shows, or other means.
不管你收藏什么，在你决定出手之前花一些时间做深入的了解和研究。找一些专业的机构和商业杂志，他们将帮助你对你的收藏品进行正确的估值，找一个最好的平台卖掉它。不管是在Ebay，本地展会还是其它的渠道。
