She picked up the coin.
Literal
She [topic-は] coin [object-を] picked-up.
拾い上げる ('pick up') is a compound verb: 拾う ('pick up off the ground, find') + 上げる ('raise, lift up'). The 上げる element adds a sense of upward motion and completion — the coin doesn't just get found, it gets lifted up. Compare 拾う on its own (more neutral, 'I found a coin') with 拾い上げる ('I picked it up off the ground') — the compound emphasizes the physical act. ~上げる is a productive compound-verb suffix appearing in 持ち上げる, 抱き上げる, 引き上げる, and many others, all carrying a 'lift up / bring to completion' flavor.
