We can use the present value formula for an annuity to calculate this:
Present value = Payment x [(1 - (1 + r)^(-n)) / r]
Where r is the interest rate per period, n is the number of periods, and the payment is the amount received each period.
In this case, the payment is $510 per year, the interest rate per period is 6.51% (or 0.0651), and the number of periods is 10.
Present value = 510 x [(1 - (1 + 0.0651)^(-10)) / 0.0651]
Present value = 510 x [(1 - 0.3763) / 0.0651]
Present value = 510 x (11.0692)
Present value = $5,639.93
Therefore, the present value of an annual payment of $510 for 10 years at an interest rate of 6.51% is $5,639.93.
