The auction company is licensed to operate, belongs to the category of pre-approval, and has compliance and legitimacy, so I say that a possible gray operation, I emphasize that it is not necessarily real, and the ** of the collection is higher through auction, for example, the auction result of an old coin is 1 million transactions, and I pay another 1 million to push the auction ** to 10 million. 
Then set up a company based on this coin, pay a certain percentage of the appraisal service fee, evaluate the lot, and then issue ABS, that is, the asset, 10 million coin collection has transaction records and appraisal reports, plus the company's cash flow and receivable guarantees, according to the 60% pledge rate to finance 6 million. 
This operation can obtain 4 million financial credit, before the real estate enterprises to draw a red line, the requirements of funds can not flow to the real estate industry, and this debt is guaranteed and held by the newly established company, real estate companies are not on the credit, seems to solve an industry pain point. 
Another value because of the numismatic collections, artworks, etc. have strong cultural attributes, but everything has a benefit and a disadvantage, the industry is full of chaos and it is difficult to distinguish between true and false, disorderly development, here I suggest that you have time to take a look at the "Celadon Celadon starring Wang Zhiwen", and carefully experience the actor-level interpretation of Yan Ruoshui and Wang Zhiwen. 
Finally, I would like to say my personal opinion, what you see is not necessarily the truth, what you think is not necessarily the truth, what you see is what others want to see for you. Numismatic Collection
