Forgeries are copies or imitations of original items, often created with the intent to deceive. This can include art, documents, or currency. For example, a forged painting might be made to look like a famous artist's work, tricking buyers into thinking it is genuine. The act of forgery is illegal and can lead to serious consequences. Forgers often use advanced techniques to replicate the original, making it difficult to detect the fraud. Law enforcement and experts in art authentication work to identify forgeries and protect the integrity of original works and documents.
