Hi,
I love Vokey wedge. Also Bob Vokey is a Canadian, in the Canadian Golf Hall Of Fame, and is a very friendly person.
I think, he is making the best wedge on the market since a very long time.
But, I would not consider to collect wedges.
The reasons are 1) a wedge, when put in play deteriorate with the use of it, 2)with the success of Bob Vokey products, there is a big quantities of used Vokey wedge on the market and resale value are lower, 3) Bob Vokey and Titleist are improving the products every 2 years or so.
You always find a client for a use Vokey wedge.
But, I remember some Vokey wedges that I sold and I regret after. I was liking a lot those made in copper color, I think oil can.

I would more consider to collect Scotty Cameron putter. Even if used, these putters keep an excellent market value. They are also easy to sell and when you take care of them the deterioration is minimal.

You could have a different approach and if you are happy to collect them do it.
I am doing the same thing with fly fishing rods that I like.

Wishing a very good year for 2021 to all.
