Undoubtedly. Although I believe less on eBay, which I feel has gone off the boil and is mostly blatant tat to surely even the most naive of newbies, and more on the newer Facebook 'collector groups' Many of which are simply selling platforms for the people who set them up with the occasional 'educational' post chucked in to retain interest as they flog their wares.
I often see comments praising what, to me, appear to be fairly run of the mill examples of a coin. Which makes sense to me, since I personally feel I'm still learning! Despite spending the last decade or so recording examples of what I collect, there are still occasions where it dawns on me how very few coins of a particular variety or mint mark I've actually seen. On that point, I'm always guided by Richard Lobel's the Coincraft Catalogue where he quotes his mentor saying " 'when you go to value a coin it is what you have not seen rather than what you have seen that matters'. By [which] he meant that, when you see a coin that you have never seen before, forget what it catalogues, it is rare! "
Newer collectors I'm sure think what they are seeing must be the 'finest ever' - aided in some cases by the TPGS claims - when in actual fact a quick search on the BM website or on CoinArchive.com would quickly disabuse them. And of course, presumably down to Covid in part, people aren't spending on holidays and meals out and are quick to splash their cash on collectables. Hence the silly money we're seeing now, which some - presumably - see as normal.
I don't know what the future will be like. I feel as a collector, I'm approaching the limit of my budget, but that's not really new! Every now and then I see something I can manage - often a conditional rarity - or get tempted by something new - I've recently bought a few historic medals related to Charles I because they're attractive, historically connected and, compared to some of the coins, not too expensive. But I've had to accept that I will never have a fully representative collection due to the scarcity of some of the types in the series and, often more a factor than the rarity, the fact that some examples only exist in grades that I'd struggle to live with. Yes, I'm shallow! But I like to get a buzz when I look at my collection and that generally means a coin has to meet an aesthetic benchmark for me to consider it.
Sadly (?) many of the coins I'd like currently live in other people's collections. And are likely to stay there for the foreseeable future. I therefore have to accept that the best I can hope for is to be considered a minor, but careful, collector for whom eye appeal was important.
God, that was me before I've even had a beer! Sorry. I'll shut up now.
