if this foreign currency is UNC, it means that the appearance of this foreign currency is brand-new. Therefore, the new appearance has nothing to do with whether foreign currency can be used: a UNC dollar and a crumpled dollar can also be circulated in the market, and the purchasing power is the same.
Extended information:
Foreign currency collection is a very small collection item, and my RMB collection has reached the bottleneck, so I turned to this direction. Compared with RMB collection, foreign currency collection has the following characteristics
First, the investment is small. Due to the fierce domestic speculation, most versions of RMB in the 198s and before need four-digit investment. The first set and the second set are almost impossible for ordinary enthusiasts, while foreign currency is much easier. After the 195s, except for the face value, the premium rate was significantly lower than that of all versions of RMB.
Second, there are many versions. The new version of RMB usually takes ten years (as most East Asian countries do). Because foreign currency is signed, signature replacement usually leads to version replacement. For example, Hong Kong has a new date almost every year. If you stick to the full set of each version like RMB, the economic pressure will be great.
thirdly, it is systematic. There are many countries in the world, but there are actually not many printing institutions. Except for developed countries, most of them are printed by other countries. Therefore, there is always a feeling of deja vu in foreign currency collection, such as familiarity with TDLR's number fonts, rainbow printing, honeycomb lattice, multi-color machine-carved patterns, linear security lines to miniature text security lines in the 198 s and 199 s. If you get a new banknote, you will find that it is just a simple repetition, and the sense of acquisition will be greatly reduced.
Fourth, it should be directional. Foreign currency collection is a modest pit, and the demand is not high, so it won't cost much. Sticking to the big set will also encounter bottlenecks, such as my direction is technology and culture. Other Tibetan friends include the direction of western Europe, the direction of the euro zone, the direction of the portrait of the queen, etc. Even if the direction is determined, sometimes they will start when they see the favorite banknotes.
Fifth, it is difficult to sell. The old version of RMB has a fair value in the market, and it is easy to sell slightly below the market price. Foreign currency? I haven't sold it since 213, which is also related to my caution before starting.
