在日常生活中人們總是不斷在辨識各種物體及圖像，通用中的貨幣當然也需要進行真偽辨識。心理家的研究指出，人們對於辨識極為熟悉的事物，大都是以猜測的方式進行，屬於一種感官性的辨識模式。本研究藉由人們熟悉的現行新台幣五十元之硬幣，進行硬幣圖像的辨識研究，了解受試者對於硬幣圖像的辨識正確率及圖像認知記憶程度，採用問卷法與實驗法混合進行，以30 位前測受試者的測試結果，進行32 種不同硬幣實驗圖像的模擬設計，再以100 位受測者進行正式測試，並接受五十元硬幣圖像之辨識正確率的實驗測試。問卷數據分別進行次數分配與獨立樣本T 檢定的分析，研究結果顯示：受測者對於五十元硬幣正反面圖像的辨識正確度，普遍均達到五成左右的辨識正確率，較容易產生混淆的硬幣圖像，是與實際硬幣圖像較為相似的圖像，或曾經在其他面額硬幣中出現過的圖像，另外，硬幣上不同的文字的排列法，也容易產生硬幣圖像辨識度的混淆。

The visual recognition of currency is important in our everyday life. Psychologists indicate that people always recognize familiar things by styles of guess. In this study, the icons of fifty-dollar coins are used to realize the recognition and memory of users. There are 30 people for pre-testing and then 32 coin-coins for testing by questionnaires and experiments. The results are analyzed by Number-Distribution and T-Testing with independent samples. The results show that the probability for correctly recognizing the icons on each face of coins is about 50%. The coin-icons with similar icons with real coins and with icons on coins of other denomination are confusing to people. In addition, the alignment of texts on coin-icons are also confusing to people.
