Will Rise In Interest Rates Lower Values / Prices For Coins?

I don't think there is a crystal ball available that can give you the answers you are looking far.

Your best bet is to go with your gut feelings and buy what YOU feel is a good value for what YOU have been searching for.

Inflation tends to make the price of everything increase, or, from another point of view, the value of the currency falls so you need more of it to buy the same things. So I would thus expect the price of coins to go up during a period of inflation.

As for the immediate impact of rate rises, it's my observation that even in the good times of near-zero interest rates, people generally don't borrow money in order to buy coins. Most people who buy coins, are wealthy enough to have "spare money" to spend on non-essentials, and they are choosing to spend that spare money on coins. Struggling families with low incomes, high debt levels and high mortgage repayments generally aren't big buyers of coins. High interest rates theoretically will eventually flow on to increased interest payments on saved money, which should mean that those wealthy enough to be earning interest, should be able to earn more interest and thus have more money to spend. Which is of course eventually counteracted by the inflationary cycle raising the prices of everything, but in the medium term, the top end of town has more free money available, which will in turn lead to higher demand and thus a higher-than-baseline-inflation-rate price increase for luxury non-essentials like coins.

So my recommendation would be to by now, and sell later.

Of course, if everyone follows this advice, it becomes a self-fulfilling prophecy.

High end will stay high, everything else will drop. I think people in the future will regard 2020-2022 as the benchmark of when all coins were priced high.

A lot of the coin shops by me are selling their morgans/peaces at $28-$31 a piece! I don't see how these prices can stay that high unless a lot of them are involved in money laundering
