ASP.NET MVC USD Currency Validation

In my ViewModel, I have the following System.ComponentModel.DataAnnotations on a property that contains USD currency:

[DisplayFormat(DataFormatString = "{0:C2}")]
[Range(0.01, 100000, ErrorMessage = "Payment amount is required between .01 and $100,000.")]
[DataType(DataType.Currency)]
[DisplayName("Payment Amount")]
public Double PrinAmount { get; set; } = 0.00;

When I enter a value of $10.005, I get the following validation model error from the ModelState.IsValid check:

The value '$10.005' is not valid for Payment Amount.

When I enter a value 10.005, the ModelState.IsValid is equal to true.

What do I need to do to modified the validation to capture both formats as invalid?

You can use Regular Expression;

[RegularExpression(@"^\d+\.\d{0,2}$")]

the DataAnnotations above ensures 2 digits.
