How many proof coins are in a 2009 Lincoln coin set?
Could you please clarify for me the exact composition of the 2009 Lincoln coin set you're referring to? As far as I'm aware, there are multiple variations of such sets, and the number of proof coins included can vary. For instance, some sets might include only a single proof coin, whereas others may feature multiple proofs alongside uncirculated or other types of coins. Without more specific information about the particular set you're inquiring about, it's difficult to provide an accurate answer to your question. Would you happen to have any additional details that could help narrow down the scope of my response?
